Chapter 18, Problem 7RQ
You are part of an engineering firm on contract with the U.S. Department of Energy’s Energy Efficiency and Renewable Energy task force to develop a program to help consumers measure the efficiency of their home appliances. Your job is to write a program that measures the efficiency of stove-top burners. Before using your program, the consumer will place a pan of room-temperature water on the stove (with + gallon of water), record the initial room temperature in units of degrees Fahrenheit, turn on the burner, and wait for it to boil. When the water begins to boil, the consumer will record the time in units of minutes it takes for the water to boil. Finally, the consumer will look up the power for the burner provided by the manufacturer.
The output of your program should look like the following output, where the highlighted values are example responses typed by the user into your program. Note that your code should line up the energy and power calculations as shown. In addition, your code must display the efficiency as a percentage with one decimal place and must include a percent symbol.
Sample Input/Output
Household Appliance Efficiency Calculator: Stove
Type the initial room temperature of the water [deg E]: 68 Type the time it takes the water to boil [min]: 21 Type the brand name and model of your stove: Krispy 32-Z Type the power of the stove-top burner [W]: 1200
Energy required: 1267909 J
Power used by burner: 1006 W
Burner efficiency for a Krispy 32-Z stove: 83.9

In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.

While constructing a building, an engineer need to fix
two steel beams together using a bracket as shown
in Figure 1. Using absolute coordinate system,
construct a G-code program for drilling hole number
3 only. To remove the metal chips the hole should be
done in three equal steps. During the drilling, coolant
should be on before spindle starts and stop after
spindle stops. The spindle speed set to 1750 RPM.
Drilling bit in rack number 2 and it should be 1 mm
over the work piece. Drilling feed rate is 20 mm/min.

For Questions 3 and 4: A cup of water was heated to a
temperature of 90°. It was placed in a refrigerator that had a
temperature of 11°C. The water cooled to a temperature of
17°C in 30 minutes. Let the following variables represent
the relevant quantities.
L = Temperature of the liquid
S= Temperature of the surroundings
t = Time
B = Initial temperature of the liquid (Temperature at t = 0
k = Cooling constant
3. Using the Equation Solver, find the value of k in the
equation L = (B - S)e -kt + S. Remember to set the
equation equal to zero and then enter it into the Solver.

- Solve question 2 based on the answer of question 1. You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU: 1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon Natural Gas BTU= 80,698,000 Oil BTU = 71,512,440 The home that used a natural gas furnace used more energy for heating. 2.- You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of the fuel.
