2) The energy consumed by a shower for 30 days is 22kwh. It is known that the resistance of the showerhead is 20 ohms and that its nominal current is 15A. So, what is the time in minutes that the shower was turned on during this period?
You have decided now that quarantine is about over to take a trip to Hawaii. You decide to rent a small house that has floor to ceiling windows. It is small so it is one floor. The length and width of the windows are 9m x 14m. There are 4 of them. It is a constant 950F (350C) outside and you really like it 650F(180C) inside. You have an air conditioner that operates at 75 percent Carnot efficiency. The windows are 6cm thick and the rest of the house is well insulated. a) How much electrical energy do you use in a day? b) What is the cooling capacity each day?
