A heat pump is used to heat water at 60°C. Heat is taken from the ground at 2°C. The observed coefficient of performance is 2.2 while the energy current associated with heating

has a magnitude of 1.0 kW. (a) How large is the rate of production of entropy? (b) How

large is the loss of available power? Show that it is equal to the product of the rate of generation of entropy and the temperature of the environment. (c) How large is the second law

efficiency of the heat pump?
