A Si solar cell has a metallic grid (fingers) of 9.6 cm length and 4 mm spacing.These fingers are formed by screen printing of aluminum paste which yields fingers thickness of 20 m. The bulk resistivity of aluminum metal is 11ohms cm. (i) Design the metal finger width in a way that the loss of power by current flow in the fingers is limited to a maximum of 30 mW for the solar cell being operated at a maximum power corresponding to a current density of 25 mA/cm2. (ii) Calculate the power loss due to the shading for this grid (fingers) design.

Answers

Answer 1

(i) The metal finger width should be designed to limit the power loss by current flow to a maximum of 30 mW. (ii) Without specific information on shading pattern or amount of shading, the power loss due to shading cannot be calculated.

What are the key factors to consider when designing an efficient and sustainable building?

(i) To limit the power loss by current flow in the fingers to a maximum of 30 mW, we can calculate the maximum allowable resistance using the formula:

Maximum power loss = (Maximum allowable resistance) x (Maximum power)^2

Since the current density is given as 25 mA/cm2 and the length of the fingers is 9.6 cm, the total current passing through the fingers is:

Total current = (Current density) x (Length of fingers)

             = (25 mA/cm2) x (9.6 cm)

             = 240 mA

Now we can calculate the maximum allowable resistance:

Maximum allowable resistance = (Maximum power loss) / (Total current)^2

                          = (30 mW) / (0.24 A)^2

                          = 520.83 ohms

The resistance of the fingers can be calculated using the formula:

Resistance = (Resistivity) x (Length) / (Cross-sectional area)

To find the width of the fingers, we rearrange the formula as:

Width = (Resistivity) x (Length) / (Resistance)

Given that the resistivity of aluminum is 11 ohms cm, the length is 9.6 cm, and the thickness is 20 µm (or 0.02 mm), we can substitute these values into the formula to find the width.

(ii) The power loss due to shading can be calculated by multiplying the shaded area by the resistance per unit area. However, without information on the shading pattern or the amount of shading, it is not possible to provide a specific calculation for the power loss.

Answers

The total weekly cost of electricity for the business is obtained by multiplying the electricity rate by the weekly electricity consumption.

What is the total weekly cost of electricity for the business?

To determine the weekly cost of electricity for the business, we need to calculate the total energy consumption and multiply it by the cost per unit.

- Two 3 kW electrical fires running for 20 hours per week each consume:

  Total energy = 2 * (3 kW * 20 hours) = 120 kWh

- Six 150 W lights running for 30 hours per week each consume:

  Total energy = 6 * (0.15 kW * 30 hours) = 27 kWh

- Total energy consumption = 120 kWh + 27 kWh = 147 kWh

- Cost of electricity = Total energy consumption * Cost per unit = 147 kWh * £0.14/kWh

The weekly cost of electricity to the business can be calculated by multiplying the total energy consumption by the cost per unit, which will give the final cost in pounds (£).

A point M is 20 mm above HP and 10 mm in front of VP. Both the front and top views
of line MN are perpendicular to the reference line and they measure 45 mm and 60 mm respectively. Determine the true length, traces and inclinations of MN with HP and VP

Answers

The true length of MN is 75 mm. Its traces intersect HP at a point 55 mm from the reference line, and VP at a point 65 mm from the reference line. The inclination of MN with HP is 51.34° and with VP is 38.66°.

To find the true length of MN, we can use the Pythagorean theorem in the top view, where the length is given as 60 mm, and the front view, where the length is given as 45 mm. Therefore, the true length is √(60^2 + 45^2) = 75 mm.

The traces of MN on HP and VP can be determined by projecting the endpoints of MN onto the respective planes. Since M is 20 mm above HP, the trace on HP will intersect HP at a point 20 mm above the reference line. Similarly, since M is 10 mm in front of VP, the trace on VP will intersect VP at a point 10 mm in front of the reference line.

To find the inclinations of MN with HP and VP, we can use the ratios of the true length and the projections of MN onto HP and VP. The inclination with HP is given by arctan(20/55) ≈ 51.34°, and the inclination with VP is given by arctan(10/65) ≈ 38.66°.

How is the contrast defined as the dynamics in gray value images? Explain it using a histogram! 2. How do homogeneous and inhomogeneous point operations differ? Which are the similarities? 3. Why is the sum of the filter core values always 0 for edge detection filters? 4. What do the Sobel filters look like? Why do you need two filter masks?

Answers

Sobel filters are commonly used in image processing for edge detection. They are gradient-based filters that highlight the edges in an image by measuring the intensity changes between neighboring pixels.

1. Contrast in gray value images is a measure of the difference between the brightest and darkest pixels in an image. It represents the dynamic range of gray values. One way to understand contrast is by analyzing the histogram of an image. The histogram displays the distribution of pixel intensities, with the x-axis representing the gray values and the y-axis indicating the frequency of occurrence. A higher peak or a wider spread in the histogram indicates higher contrast, as it signifies a larger range of gray values present in the image. Conversely, a narrow or compressed histogram indicates lower contrast, with fewer variations in gray values.

2. Homogeneous and inhomogeneous point operations both involve modifying the pixel values of an image. The difference lies in how the modifications are applied. Homogeneous point operations apply the same transformation to all pixels in an image, such as brightness adjustment or contrast enhancement. In contrast, inhomogeneous point operations vary the transformation based on the characteristics of each pixel or its local neighborhood, allowing for more adaptive adjustments. The similarity between the two is that both types of operations aim to modify pixel values to achieve specific image enhancement goals.

3. The sum of the filter core values is often set to 0 for edge detection filters to ensure that the filter is sensitive to edges and not affected by the overall intensity level of the image. By setting the sum to 0, the filter responds primarily to the intensity variations across edges, enhancing their visibility. If the sum were non-zero, the filter would also respond to the average intensity level, which could lead to unwanted artifacts or blurring in the output.

4. Sobel filters are commonly used for edge detection in image processing. They consist of two filter masks, one for detecting vertical edges (Sobel-x) and the other for detecting horizontal edges (Sobel-y). These filters are typically represented by 3x3 matrices with specific coefficients. The Sobel-x filter emphasizes vertical edges, while the Sobel-y filter highlights horizontal edges. By applying both filters, you can detect edges in different directions and combine the results to obtain a more comprehensive edge map. The combination of Sobel-x and Sobel-y filters allows for edge detection in multiple orientations.

To determine the fan power input in both scenarios, we need to use the fan affinity laws, which describe the relationship between fan speed, volume flow rate, pressure, and power. The fan affinity laws state the following relationships:

1. Volume Flow Rate (Q): Q₁/Q₂ = (N₁/N₂)

2. Pressure (P): P₁/P₂ = (N₁/N₂)²

3. Power (P): P₁/P₂ = (N₁/N₂)³

We can use the pressure relationship to find the new pressure P₂:

Substituting the given values: N₁ = 1440 rpm, N₂ = 1260 rpm, P₂ = 500 Pa, we can calculate the power input: P = (1440/1260)³ * 500 P ≈ 801 Watts Therefore, the fan power input, when the fan speed is reduced to deliver 1.8 m^3/s, is approximately 801 Watts.

A four-pole wave-connected DC machine has 48 conductors with an

resistance if the machine is rewound for lap winding.

Answers

The equivalent armature resistance for the rewound lap winding configuration is 0.0325 Ω.

To determine the equivalent armature resistance for a DC machine rewound for lap winding, we need to consider the number of parallel paths in the winding. In a four-pole wave-connected DC machine, each pole has 48/4 = 12 conductors.

For a lap winding, the number of parallel paths is equal to the number of poles, which is 4 in this case. Therefore, each parallel path will have 12/4 = 3 conductors.

Since the armature resistance is inversely proportional to the number of parallel paths, the equivalent armature resistance for the lap winding configuration will be 1/4 of the original resistance. Thus, the equivalent armature resistance is 0.13 Ω / 4 = 0.0325 Ω.

B) This type of lubrication regime is called boundary lubrication regime.

How can a substantial lubricant film be generated in journal bearings with low surface speeds?

A) When surface speeds are too low to generate hydrodynamic lubrication in a journal bearing, a thick lubricant film can still be produced through the use of boundary lubrication.

Boundary lubrication relies on the presence of additives in the lubricant that form a protective layer between the contacting surfaces, preventing direct metal-to-metal contact.

These additives can include anti-wear agents, extreme pressure agents, and friction modifiers.

The thick lubricant film is formed by the deposition of these additives onto the bearing surfaces, creating a barrier that reduces friction and wear.

To find the internal diameter of the tire, we can use the formula for hoop stress: hoop stress = (E * (d2 - d1)) / (2 * r), where d1 is the internal diameter, d2 is the external diameter (1.2 m), E is the Young's modulus (200 kN/mm2), and r is the radius. Rearranging the formula, we can solve for d1 and substitute the given values to find the internal diameter.

To find the least temperature for the tire to be heated, we use the formula: ΔL = α * L * ΔT, where ΔL is the change in length, α is the coefficient of linear expansion (6.5 x 10^-6 per °C), L is the original length (circumference), and ΔT is the change in temperature. Rearranging the formula, we can solve for ΔT and substitute the values to find the required temperature increase.

The transient response of a system subjected to unit step shows the peak value of 1.65 at 0.72 sec. and it settles after 8.4 sec. within ±2% error.
Determine:
1) The damping ratio
2) The undamped natural frequency:

Answers

1..)The value of the damping ratio is approximately 0.389

2..)The value of the undamped natural frequency is 5.95 rad/sec.

The settling time is defined as the time it takes for the response to reach and stay within 2% of its steady-state value. The time taken for the response to reach the first peak is the time period. The first peak value can be used to determine the amplitude of the response.

Using the given data, we can evaluate the damping ratio and the undamped natural frequency as follows:

`t_p = 0.72 sec`, `A = 1.65`, `T_s = 8.4 sec`, `ζ = ?`, `ω_n = ?`

We know that the peak time (t_p) is given as:`t_p = π / (ω_d*sqrt(1 - ζ^2))`

Using this equation, we can determine the damped frequency (`ω_d`) as follows:`t_p = 0.72 sec = π / (ω_d*sqrt(1 - ζ^2))` `=> ω_d*sqrt(1 - ζ^2) = π / 0.72 sec` `=> ω_d*sqrt(1 - ζ^2) = 4.363` …(i)

Next, we can evaluate the settling time in terms of the damping ratio and the undamped natural frequency.

This is given by:`T_s = 4 / (ζω_n)`

We can rewrite this equation in terms of `ζ` and `ω_n` as follows:`ζω_n = 4 / T_s` `=> ω_n = 4 / (ζT_s)` …(ii)

From Eq. (i), we can obtain the value of `ω_d` as:`ω_d = 4.363 / sqrt(1 - ζ^2)`

Substituting this value in Eq. (ii), we get:`ω_n = 4 / (ζT_s) = 4.363 / sqrt(1 - ζ^2)` `=> 1 / ζ^2 = (T_s / 4)^2 - 1 / (4.363)^2`

Solving for `ζ`, we get:`ζ = 0.389` (approx)

Substituting this value in Eq. (i), we can evaluate the value of `ω_d` as:`ω_d = 5.95 rad/sec`

Hence, the damping ratio is 0.389 (approx) and the undamped natural frequency is 5.95 rad/sec.

You work for a gas turbine design company and have a client who has a fairly loose specification for a gas turbine engine. You are required to design an aviation gas turbine to power the aircraft with minimum thrust requirement of 110,000 N from one engine. Though the client wants to achieve lowest fuel consumption possible. The following guideline efficiencies have been given to assist in the design process.
Fan, compressor and turbine polytropic efficiencies 90%
Propelling nozzles isentropic efficiencies 94%
Mechanical transmission of each spool 96%
Combustion efficiency 99%
You have total discretion to assume the temperatures, pressures and any other variable you deem necessary unless stated above, though assumptions need to be of sensible values that are justified given current engineering technology.
Your brief summary report should include as a minimum the following;
1. Discuss selection of different components and types. You need to demonstrate why a particular type/component or value has been selected as compared to others. Your answers could have both numerical and theoretical response to this part.
2. Specific Fuel Consumption
3. Thrust calculations of all nozzles.
write equations and draw diagrams by hand.
Explain the impact, if above design is run on one different fuel (eg, Hydrogen, CH4, bio fuels, etc). Answers should cover both numerical and conceptual response.

Answers

The design involves selecting components, calculating specific fuel consumption, and determining thrust calculations.

In designing the gas turbine engine, several components need to be carefully selected to meet the client's requirements. The following choices have been made based on their efficiencies and suitability for the given specifications:

1. Fan, compressor, and turbine: Considering the guideline polytropic efficiencies of 90%, we would select axial flow compressors and turbines. Axial flow components offer high efficiency in converting fluid energy into work. These components will have a high compression ratio and expansion ratio to maximize efficiency while meeting the minimum thrust requirement.

2. Propelling nozzles: The guideline isentropic efficiency of 94% indicates that convergent-divergent (CD) nozzles should be employed. CD nozzles allow for efficient expansion of exhaust gases, maximizing the thrust generated.

3. Mechanical transmission: With a mechanical transmission efficiency of 96%, we can choose an appropriate gearbox system to transmit power from the engine's high-pressure spool to the fan and low-pressure spool. This ensures efficient power transmission and overall system performance.

To calculate specific fuel consumption (SFC), we need to determine the amount of fuel consumed per unit of thrust produced. SFC is typically measured in kg of fuel consumed per hour per unit of thrust (such as kg/hr/kN). The SFC calculation involves considering the heating value of the fuel, the combustion efficiency, and the thermal efficiency of the engine. With the given combustion efficiency of 99%, we can calculate SFC using the known values and assumptions about temperature, pressure, and other variables.

For thrust calculations of all nozzles, we need to apply the isentropic efficiency of 94% to determine the specific exit velocity of the exhaust gases. By considering the mass flow rate and the velocity of the exhaust gases, we can calculate the thrust generated by each nozzle using the momentum equation.

Regarding the impact of running the above design on different fuels, such as hydrogen, CH4 (methane), or biofuels, the response would involve both numerical and conceptual considerations. Each fuel has different combustion characteristics, calorific values, and combustion efficiencies, which would affect the specific fuel consumption and overall engine performance. The impact of using different fuels would require recalculating SFC and assessing the potential changes in combustion efficiency, heating value, and emissions.

The fluid flows through constant cross sectional device with adding heat to the flow. For a compressible fluid describe in detail the relationship between (a) The mass flow rate at the inlet and outlet, and (b) The volume flow rate at the inlet and outlet.

Answers

(a) The mass flow rate at the inlet and outlet of a constant cross-sectional device for a compressible fluid is equal. (b) The volume flow rate at the inlet and outlet of a constant cross-sectional device for a compressible fluid can vary due to changes in fluid density.

What is the relationship between the pressure and velocity of a compressible fluid flowing through a constant cross-sectional device?

(a) The mass flow rate at the inlet and outlet of a constant cross-sectional device for a compressible fluid is related by the principle of mass conservation, also known as the continuity equation. According to this principle, the mass flow rate remains constant along a streamline in an ideal fluid flow. Therefore, the mass flow rate at the inlet (ṁ₁) is equal to the mass flow rate at the outlet (ṁ₂), given by the equation:

ṁ₁ = ṁ₂

This means that the mass of the fluid entering the device per unit time is equal to the mass of the fluid leaving the device per unit time. The mass flow rate represents the amount of mass passing through a specific cross-sectional area per unit time and is typically measured in kilograms per second (kg/s).

(b) The volume flow rate at the inlet and outlet of a constant cross-sectional device for a compressible fluid is not necessarily constant. Unlike the mass flow rate, the volume flow rate can change along a streamline due to changes in fluid density. The relationship between the volume flow rate at the inlet (Q₁) and outlet (Q₂) is determined by the density of the fluid.

The volume flow rate is given by the equation:

Q = A * V

where Q represents the volume flow rate, A is the cross-sectional area through which the fluid is flowing, and V is the velocity of the fluid.

In a compressible flow, the density of the fluid can change due to variations in pressure and temperature. As a result, even if the mass flow rate remains constant, the volume flow rate can vary at the inlet and outlet due to changes in fluid density.

Therefore, there is no direct relationship between the volume flow rate at the inlet and outlet of a constant cross-sectional device for a compressible fluid. The volume flow rate will depend on factors such as changes in fluid density, temperature, and pressure along the streamline.

Explain the term 'wing divergence'
Using a diagram, explain the mechanism that causes wing divergence. Describe the flight conditions under which divergence is most likely and what properties or weaknesses in a wing might cause a low divergence speed

Answers

Wing divergence refers to a phenomenon in aerodynamics where the wing structure experiences a sudden increase in bending and twisting deformation, leading to potential failure. This occurs when the aerodynamic loads acting on the wing exceed the structural strength of the wing, causing it to deform beyond its elastic limits.

To understand the mechanism of wing divergence, let's consider a simplified diagram of a wing cross-section:

```

        |<---- Torsional Deformation ---->|

        |                                 |

        |                |--- Wing Root ---|

        |                |                |

        |-------- Span ---------------|   |

        |                             |   |

        |                             |   |

        |-----------------------------|---|

```

The primary cause of wing divergence is the interaction between the aerodynamic forces and the wing's bending and torsional stiffness. During flight, the wing experiences lift and other aerodynamic loads that act perpendicular to the span of the wing. These loads create bending moments and torsional forces on the wing structure.

Under normal flight conditions, the wing's structural design and material provide sufficient stiffness to resist these loads without significant deformation. However, as the flight conditions change, such as increased airspeed or increased angle of attack, the aerodynamic loads on the wing can reach levels that surpass the wing's structural limits.

When the aerodynamic loads exceed the wing's structural limits, the wing starts to deform, bending and twisting beyond its elastic range. This deformation can cause a positive feedback loop where increased deformation leads to higher aerodynamic loads, further exacerbating the deformation.

Flight conditions that are most likely to induce wing divergence include high speeds, high angles of attack, and abrupt maneuvers. These conditions can generate excessive lift and drag forces on the wing, leading to increased bending and torsional moments.

Weaknesses or deficiencies in the wing's design or construction can also contribute to a lower divergence speed. Factors such as inadequate stiffness, inadequate reinforcement, or material defects can decrease the wing's ability to withstand aerodynamic loads, making it more susceptible to divergence.

It is crucial to ensure proper wing design, considering factors like material selection, structural integrity, and load calculations to prevent wing divergence and ensure safe and efficient flight.
