It takes 10 kW to keep the interior of a certain house at 20°C when the outside temperature is 0°C. This heat flow is usually obtained directly by burning gas or oil. Calculate the power required if the 10 kW heat flow were supplied by operating a reversible engine with the house as the upper reservoir and the outside surroundings as the lower reservoir, so that the power were used only to perform work needed to operate the engine.

Transcribed Image Text:It takes 10 kW to keep the interior of a certain house at 20°C when the
outside temperature is 0°C. This heat flow is usually obtained directly by
burning gas or oil. Calculate the power required if the 10 kW heat flow
were supplied by operating a reversible engine with the house as the
upper reservoir and the outside surroundings as the lower reservoir, so
that the power were used only to perform work needed to operate the
engine.
