The strong extract solution will contain 10 per cent CuSO, and 90 per cent water. Since CuSO, is the valuable constituent, 97 per cent of it must be recovered in the extract. The gangue retains 1.5 tons of water per ton of gangue.
a) Calculate the FLOW RATES and CONCENTRATIONS from EACH STAGE in the extraction system consisting of 8 (EIGHT) stages.

An ideal diesel engine uses air as the working fluid. The state of the air at the beginning of the compression process is 95 kPa and 20°C. If the maximum temperature of the cycle is not to exceed 2200 K, determine (a) the thermal efficiency and (b) w_net
The diesel cycle is a thermodynamic cycle used in diesel engines, which is distinct from Otto's cycle. In this cycle, compression and ignition occur in the cylinder, rather than externally as in Otto's cycle.
The air is compressed, causing it to heat up, and diesel is injected. The fuel ignites, causing an increase in pressure, which forces the piston down, generating power. The exhaust is removed after this. The compression ratio is quite high in diesel engines since they operate on the diesel cycle.
An ideal diesel engine is a heat engine that burns diesel fuel and air in a closed piston cylinder to produce power. The heat released during combustion is used to raise the temperature and pressure of the gas. As the gas expands, the piston is pushed down, converting the heat energy into mechanical energy.

Required information The "divide and average" method, an old-time method for approximating the square root of any positive number a, can be formulated as follows: X = fraq_{x+alx} {2} Use the well-structured function developed for the given algorithm to calculate the estimated value, the approximate relative error(%), and the number of iteration for the following data: Value for which square root is to be computed: 16 Stopping criterion: 0.001 (Round the estimated value and the approximate relative error to four decimal places and the number of iterations to the nearest whole number.) The estimated value = The approximate relative error = e The number of iteration =
The estimated value = 4.2426, the approximate relative error = 0.0052, and the number of iterations = 3.
Given data: Value for which square root is to be computed: 16, stopping criterion: 0.001.The Divide and average method, an old-time method for approximating the square root of any positive number a, can be formulated as follows: X = fraq_{x+alx} {2}
Here, to calculate the square root of 16 using the divide and average method, we have to perform the following calculations:
i) Substitute a = 16, x = 1 and l = 0.
ii) Calculate the value of X using the formula X = fraq_{x+alx} {2}
iii) Compare the values of X and x. If the difference between them is less than the stopping criterion, the calculation is stopped. Otherwise, the value of X is taken as the new value of x and the calculation is continued using the new value of x. The steps are repeated until the difference between the old value of x and the new value of x is less than the stopping criterion.
iv) Count the number of iterations needed to obtain the required accuracy.Applying the above formula we get:
$X = \frac{1}{2} \left( X + \frac{16}{X}\right)$Given that, a = 16 and x = 1We can find out the value of X by putting these values in the given formula:
$X = \frac{1}{2} \left( 1 + \frac{16}{1}\right) = \frac{17}{2}$
Now we will check whether the stopping criterion is achieved or not. For this, we will repeat the above process until the error is less than or equal to the stopping criterion.Let us calculate X for the first iteration.
$X = \frac{1}{2} \left( 1 + \frac{16}{1}\right) = \frac{17}{2} = 8.5000$
After the first iteration, we get X = 8.5. The error can be calculated as the difference between the current value of X and the previous value of X i.e.,$e_1 = \frac{|X_{new}-X_{old}|}{X_{new}} = \frac{|8.5 - 1|}{8.5} = 0.8824$
Since the error is greater than the stopping criterion i.e., 0.8824 > 0.001, we need to repeat the process.
Let us calculate X for the second iteration.$X = \frac{1}{2} \left( 8.5 + \frac{16}{8.5}\right) = \frac{145}{34} = 4.2647$
After the second iteration, we get X = 4.2647. The error can be calculated as the difference between the current value of X and the previous value of X i.e.,
$e_2 = \frac{|X_{new}-X_{old}|}{X_{new}} = \frac{|4.2647 - 8.5|}{4.2647} = 0.9947$
Since the error is greater than the stopping criterion i.e., 0.9947 > 0.001, we need to repeat the process.
Let us calculate X for the third iteration.$X = \frac{1}{2} \left( 4.2647 + \frac{16}{4.2647}\right) = \frac{6971}{1634} = 4.2426$
After the third iteration, we get X = 4.2426. The error can be calculated as the difference between the current value of X and the previous value of X i.e.,
$e_3 = \frac{|X_{new}-X_{old}|}{X_{new}} = \frac{|4.2426 - 4.2647|}{4.2426} = 0.0052$
Since the error is less than or equal to the stopping criterion i.e., 0.0052 ≤ 0.001, we stop the process.
The estimated value of the square root of 16 is X = 4.2426, the approximate relative error is e = 0.0052, and the number of iterations required is 3. Therefore, the estimated value = 4.2426, the approximate relative error = 0.0052, and the number of iterations = 3.

9. (20 Points) Find a formal power series solution to the following one dimensional wave equation Ytt = 16 yaz; y(0,t) = y(«,t) = 0, y(t,0)=1, 4(1,0) = sin(51). (Hint: You can solve this problem without computing any integrals (provided you did the previous problem))
We can assume that the solution can be written as a power series in t. To find a formal power series solution to the one-dimensional wave equation, Let's denote the solution as y(t) = Σ(an tn), where an are coefficients to be determined.
We'll differentiate y(t) with respect to t to find yt(t) and ytt(t), and then substitute these derivatives into the wave equation to determine the coefficients an.
Differentiating y(t) with respect to t:
yt(t) = Σ(n * an * tn-1)
Differentiating yt(t) with respect to t:
ytt(t) = Σ(n * (n-1) * an * tn-2)
Substituting these derivatives into the wave equation:
ytt(t) = 16 * y(t)
Σ(n * (n-1) * an * tn-2) = 16 * Σ(an tn)
Now, we'll equate the coefficients of like powers of t on both sides of the equation.
For n = 0:
-2 * a0 = 16 * a0
For n = 1:
-6 * a1 = 16 * a1
For n ≥ 2:
(n * (n-1) * an) - 16 * an = 0
Solving the above equations, we find:
a0 = 0
a1 = 0
For n ≥ 2:
(n * (n-1) - 16) * an = 0
The roots of the quadratic equation (n * (n-1) - 16) = 0 are n = -4 and n = 5.
Therefore, the solution to the wave equation is:
y(t) = a-4 t^-4 + a5 t^5
To determine the coefficients a-4 and a5, we need to use the initial conditions.
From the condition y(t,0) = 1, we have:
a-4 * (0)^-4 + a5 * (0)^5 = 1
a5 = 1
From the condition 4(yt)(0) = sin(5t), we have:
4 * (-4) * a-4 * (0)^-5 + 4 * 5 * a5 * (0)^4 = sin(5t)
-16 * a-4 = sin(5t)
Therefore, a-4 = -1/16
The final solution to the wave equation is:
y(t) = -(1/16) * t^-4 + t^5

The Voigt model (also known as the Kelvin model) consists of a spring and a dashpot in parallel.
a. By using the Hooke’s and Newton’s law, determine the governing equation of the Voigt model.
b. Determine and describe using the Voigt model the case of
i) creep.
ii) stress relaxation
a. The governing equation of the Voigt model is σ_total = E_spring * ε + η * ε_dot. b. i) Creep: In creep, a constant load is applied to the material, resulting in continuous deformation of the spring component in the Voigt model. ii) Stress relaxation: In stress relaxation, a constant strain rate is applied to the dashpot component, causing the stress in the spring component to decrease over time.
What are the key components and behaviors of the Voigt model?a. The governing equation of the Voigt model can be determined by combining Hooke's law and Newton's law. Hooke's law states that the stress is proportional to the strain, while Newton's law relates the force to the rate of change of displacement.
For the spring component in the Voigt model, Hooke's law can be expressed as:
σ_spring = E_spring * ε
For the dashpot component, Newton's law can be expressed as:
σ_dashpot = η * ε_dot
The total stress in the Voigt model is the sum of the stress in the spring and the dashpot:
σ_total = σ_spring + σ_dashpot
Combining these equations, we get the governing equation of the Voigt model:
σ_total = E_spring * ε + η * ε_dot
b. In the Voigt model, creep and stress relaxation can be described as follows:
i) Creep: In creep, a constant load is applied to the material, and the material deforms over time. In the Voigt model, this can be represented by a constant stress applied to the spring component. The spring will deform continuously over time, while the dashpot component will not contribute to the deformation.
ii) Stress relaxation: In stress relaxation, a constant deformation is applied to the material, and the stress decreases over time. In the Voigt model, this can be represented by a constant strain rate applied to the dashpot component. The dashpot will continuously dissipate the stress, causing the stress in the spring component to decrease over time.

In a 4-stage air compressor that operates between pressure limits of 101.3kPa to 2.505MPa, the total power can be determined by using the formula PV¹.² = C, if the compressor compresses 1200 m³ /min.
PV¹.² = C, and we can rewrite the equation as PV^n = C
P = pressure
V = volume
N = polytropic index
C = constant To find the value of N, we need to use the following equation:
N = log(P2/P1) / log(V2/V1)where,
P1 = 101.3 kPa,
P2 = 2.505 M Pa,
V1 = ? , V2 = 1200 m³/min
We can find V1 by using the following equation:

How are the teeth numbers of the first gear determined if it is a double stage gear box? How are the second, third, and fourth gears determined? For the second, third, fourth and fifth gears, a similar iteration process will be carried out to check shaft distance A, the axial load balance, using addendum modification if needed.
Designing a 4-speed constant mesh gearbox involves determining the main dimensions and teeth numbers of each gear stage. A layout diagram shows the gearbox when the 4th gear is engaged.
In the design process of a 4-speed constant mesh gearbox, determining the main dimensions is crucial. These dimensions include the overall size and shape of the gearbox, the distance between shafts, and the alignment of gears and shafts. The main dimensions are typically determined based on factors such as the power and torque requirements of the transmission system, the available space for installation, and any specific design constraints.
When designing a double-stage gear box, the teeth numbers of the first gear are determined based on the desired gear ratios for the transmission. The gear ratios are determined by the ratio of the number of teeth on the driver gear (connected to the input shaft) to the number of teeth on the driven gear (connected to the output shaft). By selecting appropriate teeth numbers, the desired gear ratio for each stage can be achieved.
The determination of the second, third, and fourth gears follows a similar iteration process. The designer considers factors such as the required gear ratios, the size and strength of the gears, and the desired shift pattern. Additionally, the distance between shafts (shaft distance A) and the axial load balance are checked and adjusted if necessary. Addendum modification, which involves altering the shape of the gear teeth, may be employed to ensure proper meshing and load distribution among the gears.
Overall, designing a 4-speed constant mesh gearbox involves a systematic process of determining main dimensions, selecting teeth numbers for each gear stage, and optimizing the gear arrangement to achieve the desired performance and durability.

0.085 m3/s of water is flowing in an open rectangular channel 0.2 m wide. The depth of the water is measured to be 0.255 m, and the Chezy coefficient is assumed to be 66. Determine
The Hydraulic Depth (m) Answer for coordinate 1
The slope of the channel. Answer for coordinate 2 (answer must be inputted as a decimal to five places, not a fraction. ie 0.00100 , not 1/1000)
The hydraulic depth at coordinate 1 can be calculated using the formula: hydraulic depth = (flow rate) / (channel width * measured depth)
The slope of the channel at coordinate 2 can be calculated using the formula: slope = (Chezy coefficient^2) / (channel width^2)
Hydraulic depth at coordinate 1: (0.085) / (0.2 * 0.255) ≈ 1.668 m
Slope of the channel at coordinate 2: (66^2) / (0.2^2) ≈ 8649
What is the hydraulic depth at coordinate 1 and the slope of the channel at coordinate 2, given a flow rate of 0.085 m3/s, a channel width of 0.2 m, a measured depth of 0.255 m, and a Chezy coefficient of 66?To determine the hydraulic depth and the slope of the channel, we can use the following formulas:
1. Hydraulic Depth (D):
D = A / P
Where:
A = Cross-sectional area of the flow = width * depth
P = Wetted perimeter of the flow = 2 * (width + depth)
Substituting the given values:
A = 0.2 m * 0.255 m = 0.051 m²
P = 2 * (0.2 m + 0.255 m) = 0.91 m
D = 0.051 m² / 0.91 m = 0.056 m
Therefore, the hydraulic depth at coordinate 1 is 0.056 m.
2. Slope of the channel (S):
S = (Q / (A * R^(2/3))) * (1 / n)
Where:
Q = Flow rate = 0.085 m³/s
A = Cross-sectional area of the flow = 0.051 m² (as calculated earlier)
R = Hydraulic radius = A / P = D / 4
n = Manning's roughness coefficient (assumed to be 66)
R = 0.056 m / 4 = 0.014 m
S = (0.085 m³/s / (0.051 m² * (0.014 m)^(2/3))) * (1 / 66) ≈ 0.000225
Therefore, the slope of the channel at coordinate 2 is approximately 0.000225 (rounded to five decimal places).

The sides of a thin rectangular block are measured using different digital calipers as 25.00 + 0.05 mm and 17.50 + 0.01 mm. Based on the data, the perimeter of the block is calculated as 85.0 mm by adding the length of the four sides. What is the uncertainty in the perimeter of the block expressed in mm?
The uncertainty in the perimeter of the block is approximately 0.072 mm.
To determine the uncertainty in the perimeter of the block, we need to consider the uncertainties associated with each side measurement. In this case, we have two measurements with their respective uncertainties:
Side 1: 25.00 ± 0.05 mm
Side 2: 17.50 ± 0.01 mm
To calculate the perimeter, we add the lengths of all four sides. Let's denote the sides as A, B, C, and D. The perimeter (P) can be expressed as:
P = A + B + C + D
To find the uncertainty in the perimeter, we can propagate the uncertainties of the individual side measurements using the formula:
ΔP = √((ΔA)^2 + (ΔB)^2 + (ΔC)^2 + (ΔD)^2)
where ΔA, ΔB, ΔC, and ΔD are the uncertainties associated with each side measurement.
In this case, the uncertainties are given as ±0.05 mm for Side 1 and ±0.01 mm for Side 2.
Let's calculate the uncertainty in the perimeter:
ΔP = √((0.05)^2 + (0.01)^2 + (0.05)^2 + (0.01)^2)
= √(0.0025 + 0.0001 + 0.0025 + 0.0001)

What were the engine parameters at sea level conditions if the pressure here is 101.0kPa and the temperature here is 18 C hotter than that of the elevated condition? Determine at sea-level conditions the Brake Power in kW. Use four (4) decimal places in your solution and answer.
At sea-level conditions, the Brake Power of the engine is 0.958 kW.
The parameters of the engine at the sea level conditions are: Pressure = 101.0 kPa, Temperature = 15.5 + 18 = 33.5 CFirst, we need to calculate the mass flow rate of air, ma:ma = mf / φma = 0.0184 / 0.065ma = 0.2831 kg/sWe can now determine the mass of fuel, mf, as follows: BP = mf x LHV x ηBP = (0.0184 x 43.107 x 0.82) / 1000BP = 0.0006446 kW or 0.6446 WBP = 0.6446 x 1000 = 644.6 WBP = 0.6446 kW

Explain with the aid of clearly labelled diagrams the purpose of and oper- ating principle of an automotive differential.
The purpose of an automotive differential is to allow the wheels of a vehicle to rotate at different speeds while transferring power from the engine to the wheels. This is necessary when the vehicle is taking a turn, as the outer wheel needs to cover a greater distance and therefore needs to rotate at a higher speed than the inner wheel.
Operating Principle:
The differential is located in the rear axle assembly of a vehicle and consists of several components, including a ring gear, pinion gear, side gears, and axle shafts. It operates based on the principle of torque distribution and utilizes a set of gears to achieve the desired speed differentiation.
Here is a step-by-step explanation of the operating principle:
1. Power Input: The power from the engine is transferred to the differential assembly through the driveshaft.
2. Ring and Pinion Gears: The power from the driveshaft is received by the ring gear, which is connected to the pinion gear. The pinion gear is responsible for transmitting the rotational force to the differential case.
3. Differential Case: The differential case is the central component of the differential. It houses the side gears and the spider gears.
4. Side Gears: The side gears are connected to the axle shafts. They are responsible for transferring power from the differential case to the axle shafts, which in turn rotate the wheels.
5. Spider Gears: The spider gears are located inside the differential case and serve as the main mechanism for speed differentiation. They are meshed with the side gears and rotate within the differential case.
6. Speed Differentiation: When the vehicle takes a turn, the spider gears allow the side gears to rotate at different speeds. This speed differentiation is necessary to accommodate the varying distances traveled by the inner and outer wheels.
7. Torque Distribution: As the side gears rotate at different speeds, torque is distributed to the wheels based on their rotational resistance. The wheel with less resistance (outer wheel) receives more torque, while the wheel with more resistance (inner wheel) receives less torque.
8. Differential Locking: In some vehicles, there is an option to lock the differential. This prevents the speed differentiation and forces both wheels to rotate at the same speed, which can be useful in off-road or low-traction situations.
The diagram below illustrates the components and operating principle of an automotive differential:
```
