Question

A farmer runs a heat pump using 2 kW of power input. It keeps a chicken hatchery at a constant 30°C while the room loses 10 kW to the colder outside ambient at 10°C. What is the rate of entropy generated in the heat pump? What is the rate of entropy generated in the heat loss process? 

Answer 1

Hatchery, steady state.

To have steady state at 30°C for the hatchery

C.V. From hatchery at 30°C to the ambient 10°C. This is typically the walls and the outer thin boundary layer of air. Through this goes Q_Loss
