During a cold winter day, wind at 50 km/h is blowing parallel to a 4-m-high and 10-m-long wall of a house. If the air outside is
at 0[C] and the surface temperature of the wall is 10[C], determine the rate of heat loss from that wall by convection. Assume the wall is smooth.

Answer:
a)
Explanation:
a) Let consider that heat pump is reversible, so that the Coefficient of Performance is:
The minimum heat received by the house must be equal to the heat lost to keep the average temperature constant. Hence:
The minimum power supplied to the heat pump is:
