If a carnot engine receives heat from a heat source and discharge 1000J to a heat sink at temperature of 27C in each cycle, calculate the heat received and the work performed by the engine in each cycle

You need to say what the heat source temperature is. Then the efficiency can be calculated
a carnot machine operates between a hot reservoir at 200 grade C and a cold reservoir at 20 grade C.
When operated as an engine it receives 1000 KJ/kg; find the work output.
Find the COP when operates as a refrigerator and a heat pump.
