Using the degree day method calculate the annual kwh use in springfiled il with a heat loss of 12kwh an inddor twmperature of 7
Answer:
The correct solution is "21024 KWh/degree day".
Explanation:
The given query is incomplete. Below is the attachment of complete query is provided.
The given values are:
Indoor design temperature:
= 70°F
Now,
According to the question,
The heat loss annually will be:
= [tex]12\times 24\times 365[/tex]
= [tex]105120 \ KW[/tex]
Degree days will be:
= [tex]75-65[/tex]
= [tex]5[/tex]
Hence,
Annual KWh use will be:
= [tex]\frac{Heat \ loss \ annually}{degree \ days}[/tex]
On substituting the values, we get
= [tex]\frac{105120}{5}[/tex]
= [tex]21024 \ KWh/degree \ day[/tex]
Advatnage and disadvantages of gas turbine engine ?
Explanation:
Advantages of Gas Turbine engine
1. They are small in size, weigh less and have low initial cost per unit output.
2. They are easy to install within short periods.
3. They are quick-starting and smooth running.
4. They offer flexibility by supplying electricity for power generation as well as by supplying compressed air for process needs.
5. They are capable of using a range of liquid and gaseous fuels including synthetic fuels.
6. They are subjected (put) to fewer environmental restrictions than other prime movers.
7. Water consumption is less compared to steam power plant.
Disadvantages
1. An electric motor or an I.C. engine is necessary for starting the plant. The starting motor must bring the compressor well towards the operating speed. So, starting is not simple as in the case of other power plants.
2. Gas turbine plants have less vibrations when compared with reciprocating engines of the same speed. However the high frequency noise from the compressor is objectionable.
3. High temperatures impose severe restriction on the servicing conditions of the plant.
4. Overall efficiency is low since two-thirds of the total power output is used for driving the compressor.
5. The blades of the turbine require special cooling methods due to the severity of operating temperatures and pressures. In practice, the temperatures at the entry of the turbine are as high as 1100°C - 1260°C. Hence they should be made of special metals and alloys.
6. They are incompatible with solid fuels.

It is safe to keep a cylinder next to the actual welding or cutting operation, true or false?
Answer:
Explanation:
Cylinders shall be kept far enough away from the actual welding or cutting operation so that sparks, hot s lag, or flame will not reach them. When this is impractical, fire resistant shields shall be provided. Cylinders shall be placed where they cannot become part of an electrical circuit.
Consider a system with a single light (can be on or off) that can be controlled by any one of three switches. On switch is the master on/off switch. If it is down, the light is off. When the master switch is up, the light will be on iff both the other switches are up.a. Write a Boolean function (let’s call it F) for this circuitb. Write a truth table for F.c. Draw a circuit diagram to show how F could be implemented with AND, OR, and NOT gates.

An ordered collection of data elements stored and accessed in a program is called what?
Group of answer choices
Variables
List
Locale
Parameters
Answer:
10.5
Explanation:
Convert to an equation for example P%* X=Y
P is 7.5% X is 140, so the equation Is 7.5 percent * 14= Y
convert 7.5% Into a decimal by removing the percent sign and deviding by 7.5/100= 0.075
Substitute 0.075 for 7.5% in the equation: 7.5%*140=Y becomes 0.075*140= 10.5

Explanation:It is usually most slippery ___ of rain fall
Answer:
A.) At the start
Explanation:
Roads are most slippery at the beginning of rain storms due to oil and dirt from traffic. By the end of a rain storm, the oil and dirt are more likely to have been washed off the roadway. Additionally, rain is not the only factor that can contribute to slippery roadways - and not even the most dangerous. Ice is even slipperier.

Which of these substances is the most flammable?
A) nitrogen
B) sulfur dioxide
C) butane
D) nitric oxide
E) silica
Answer:
Butane
Explanation:
Its very simple, this subtance is highly flammable, its a easily liquefied gas that vaporizes at room temperature.
Determine the design stress for bolts in a cylinder cover where the load is fluctuating due to gas pressure. The maximum load on the bolt is 50 kN and the minimum is 30 kN. The load is unpredictable and factor of safety is 3. The surface of the bolt is hot rolled and the surface finish factor is 0.9. During a simple tension test and rotating beam test on ductile materials (40 C 8 steel annealed), the following results were obtained : Diameter of specimen = 12.5 mm; Yield strength = 240 MPa; Ultimate strength = 450 MPa; Endurance limit = 180 MPa

An article that discusses pharaohs and gives examples and explains how they look. Which text structure is that?
The correct answer to this open question is the following.
The text structure of an article that discusses pharaohs and gives examples and explains how they look is a description.
The text structure called description allows the reader to fully know the characteristics of the people it is referring to, including some important details. That is why the author of a description text adds words like "such as" and "for example."
When describing something, the write is giving structure to the text and sequence. What comes first., what is followed, and so on.
That is why The text structure of an article that discusses pharaohs and gives examples and explains how they look is a description. It includes cause and effect sentences, and some comparisons in order to contrast an idea.
