Question

A steam turbine is supplied with 54 Kg/s of superheated steam at 100 bar and 420°C with negligible velocity. The shaft of the turbine produces 2200000 KNm of torque at 3500 rev/min. The heat loss is 2.3 MW from the casing of the turbine. Determine the thermal power remaining in the exhaust steam.

Take the value for enthalpy as 3155.52 kJ/kg.
