WebA basic, idealised Rankine cycle has a turbine entrance of state of 700oC and 8 MPa. The turbine operates isentropically to an exit pressure of 20 kPa (Note that this will produce a. turbine exit state that is a liquid-vapour mix). The condenser exit state is a saturated liquid at 20 kPa. The pump is isentropic. WebEngineering Mechanical Engineering Q3: A steam power plant operates on the reheat regenerative Rankine cycle with a closed feedwater heater. Steam enters the turbine at 12.5 MPa and 550°C at a rate of 24 kg/s and is condensed in the condenser at a pressure of 20 kPa. Steam is reheated at 5 MPa to 550°C. WebThe overall efficiency of both the Rankine cycle and the Carnot cycle will be identical, when there is a complete accomplishment of heat regeneration.With the steam regeneration, the efficiency of Rankine cycle can be improved more equivalent to that of Carnot cycle when both the cycles are operated between the same intervals of time. ramsay avenue reserve
