Question 50 You've met a lovely lady named Gertrude. She uses 8,068 kWh of electricity per year. She pays $0.12/kWh to the local distribution utility. She would like to go net-zero. Your co-worker has determined that shading losses will reduce total electrical generation by 2%. You plan to use an inverter that is 95.4% efficient. Assume that grid availability is 99.1%. 1kw of installed capacity will generate 1,277 kWh/year at this location, before losses are taken into account. Assuming standard losses for all other components, what is the maximum system size in kw that you would recommend that she install on her home, to 1 decimal place accuracy (do not take age-related losses into account)? While 10kw is the standard maximum for residential accounts, ignore that restriction (ie. if your answer is 15.1kw, then input 15.1) how to solve this Hand written asap

Answer question 2 based on the results 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= 80698000 Btu Oil BTU = 71512440 Btu 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 fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…

Please provide equations that you are using so I can follow along and learn how to do this. 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.
5. (a) Describe a platinum resistance thermometer. How would you calibrate and use it formeasuring temperature of an object. Mention its advantages over a thermoelectricthermometer. (Please include all the necessary and clear diagrams). (b) Discuss the second law of thermodynamics, entropy, and the principle of increase ofentropy. Show that the entropy of a reversible process remains invariant and it gets increasedin an irreversible process. (Please include all the necessary and clear diagrams).
If we wanted to supply a world of 10 billion people with an average demand of electricity at 1 kW per person, what surface area of photovoltaic arrays would be required? Compare this to the size of a known city, state or country.
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .

Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: Qt= Q0^e-kt where: ○Qt = quantity of radioactive material at time t ○Q0 = original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?

Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan An air conditioning system is used to keep the house at 65°F when the outside temperature is 85°F. The house gets heat through the walls and windows at a rate of 810 Btu/min, and the rate of heat generation inside the house from occupants, lights, and equipment is 120 Btu/min. Determine the minimum power input required for this air conditioning system.
Question 4: A person informs an engineer that he frequently feels cooler in the summer when standing in front of an open refrigerator. The engineer tells him that he is only “imagining things” because there is no fan in the refrigerator to blow the cool air over him. A lively argument ensues. Whose side of the argument do you take? Why?
