Physics – Cost of heating water in a pool?
I do not even know how to start this problem … 1. Calculate the cost (to the nearest penny) heating the water in a pool of 9 degrees F (5 degrees C) with a pool heater gas 80% efficiency. 2. Repeat the calculation if the group uses an electric heater with 80% efficiency. Pool features: diameter: 18 feet, round height: 4 feet, but the average water depth is 3.5 feet actual use of gas and electricity tariffs from utility bill Nationalgrid: gas charge equals $ 1.01 per therm electric rate is 16 cents per kilowatt-hour 1 therm = 105,480.4 kJ 1 kWh = 3600 Btu 1 cubic foot = 28.317 liters 1 liter = 1 kilogram of water 1 cal = 4.187 J 1 BTU = 1.0548 kJ
