OpenStudy (johnny1423):

To keep the inside of a building at 20 Celsius, when the temperature of the environment is -10 Celsius, we have to provide heat at a rate of 50*10^(6) cal/hour, using a heat pump. What is the minimum power that the heat pump should have, if its efficiency is maximum?

OpenStudy (cuanchi):

50*10^(6) cal? maximum means 100%?

OpenStudy (johnny1423):

\[50*10^6\]cal/hour. Maximum efficiency probably means it is a carnot engine.
