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…
A photovoltaic system is installed. It is determined that the capacity factor of the installation is 21% over the course of a year. In that year it produced 7.73 MWh. What is the size of the installation (based upon a 365-day year)?
Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.

bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.
