1.a room is to be maintained at 73 °f. the outside temperature is 92 °f. there are 11 people in the room, each generating 320 btu/hr of heat. there are 1800 watts of lighting in the room, of which 20 % goes to heat. the room has one outside wall (with no windows), which has r-8 insulation and an area of 240 ft2. the room is being cooled by air conditioners with an eer rating of 9. assume the eer rating stays constant no matter what the outdoor temperature. a.what is the heat gain in the room due to people? (include units with answer)hint #1: same units as heat generated, given in problem. b.what is the heat gain in the room due to the lighting? (include units with answer)c. what is the heat gain in the room due to heat conduction through the outside wall? (include units with answer)hint #1: r-8 means the thermal resistance is 8 (ft2-hr-°f)/btud. how much electrical power is required to run the air conditioner? (include units with answer)hint #1: eer has units of (btu/hr)/watt. use these mixed units to your advantage! e. if the air conditioner were running at the maximum possible efficiency, how much electrical power is required to run the air conditioner? (include units with answer)
