Heat Engines, Refrigerators & Second Law

A Carnot engine has an efficiency of $30\%$ . The energy is supplied to the engine at the rate of $3$ kW. The output power of the engine is

Show answer and solution

Answer: (c)

Output power $= \eta \times$ input power
$P_{out} = 0.30 \times 3000 = 900$ W
So the answer is (c) 900 W.
