Question: An engine mounted on a ship has a thermal efficiency 80% of that of the corresponding Carnot cycle. The engine receives heat from sea

An engine mounted on a ship has a thermal efficiency 80% of that of the corresponding Carnot cycle. The engine receives heat from sea at 300 K and rejects heat to atmosphere at 280 K. The work output from the engine is dissipated through an agitator to heat 500 kg of sea water to 355 K. What quantity of heat must be extracted from sea water to provide the required heating effect?
