What is the thermal efficiency of a Rankine cycle if the temperatures of its cold and hot reservoirs are and , respectively?
Estimate the Rankine efficiency of a steam power cycle. Dry and saturated steam is supplied at a pressure of 1.5 MPa. The pressure of the condenser is 400 kPa.
It is found that an engine rejects 100 J while absorbing 125 J each cycle of operation.
What is the efficiency of the engine?
How much work does it perform per cycle?
