Half of the power produced by a Carnot engine is used to operate a Carnot heat pump, which must maintain the interior of a house at 22 ° C, when the ambient temperature is 2 ° C and it is estimated that the house it has heat losses of 62,000 kJ / h. The motor is known to operate between the temperature limits of 800 ° C and 20 ° C. Determine: a) The power required to operate the heat pump b) The heat flux supplied to the motor c) The coefficient of operation of the heat pump d) The efficiency of the motor
