A geothermal air conditioning system for a small house in Upstate New York calls for cooling water at a rate of 1.3 kg/s from 24 C o to 16 C o . The house is located on a lake where the average temperature 7 m below the surface during the summer months is 14 C o . Design a heat exchanger to take the necessary energy from the geothermal cooling system water.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
