Geothermal water (c p = 1.03 Btu/lbm F) is to be used as the heat source
Question:
Geothermal water (cp = 1.03 Btu/lbm · °F) is to be used as the heat source to supply heat to the hydronic heating system of a house at a rate of 40 Btu/s in a double-pipe counter-flow heat exchanger. Water (cp = 1.0 Btu/lbm · °F) is heated from 140°F to 200°F in the heat exchanger as the geothermal water is cooled from 270°F to 180°F. Determine the mass flow rate of each fluid and the total thermal resistance of this heat exchanger.
