Question: A heat engine operates between 42.0C and 357C. Being a real engine, its efficiency is only 60% of that theoretically possible for a Carnot engine

A heat engine operates between 42.0C and 357C. Being a real engine, its efficiency is only 60% of that theoretically possible for a Carnot engine at these temperatures. If the engine absorbs heat at a rate of 50 kW, at what rate does it exhaust heat?
