engineering recuitment GATE ME 2023-24 Test Series Power Engineering Gas and Vapor Power Cycles Rankine Cycle
An ideal reheat cycle has pressure at high pressure turbine inlet equal to 9 MPa, reheat pressure equal to 1.6 MPa and exhaust pressure equal to 7 kPa. The net-work developed by the cycle is 1400 kJ/kg. Determine the enthalpy (in kJ/kg) of steam leaving the reheater, if thermal efficiency of the cycle is 38%. Temperature at turbine inlet is 500°C and steam expands to dry saturated state before entering the reheater at 1.6 MPa. Enthalpy of steam at the inlet is 3386.1 kJ/kg and at the exit is 2791.7 kJ/kg for high pressure turbine. Enthalpy of water at the exit of pump is 151.5 kJ/kg.
