In an ideal reheat-regenerative cycle, steam enters the engine at 8 MPa and 400°C. After expansion to 280°C the steam is withdrawn and reheated to 340°C. Extractions for feedwater heating occur at 1.6 MPa and 0.70 MPa and the condenser pressure is 0.005 MPa. For the ideal cycle find Wnet and e

The engine on a steam ship runs on the Rankine cycle. The steam leaves the boiler at 20 bar and 350°C. The turbine has an efficiency of 75% and an outlet pressure of 1 bar. The pressure changes in the boiler and condenser can be considered negligible, and the liquid leaving the condenser is saturated. A. Determine the operating temperature of the condenser, and compute the efficiency of a Carnot cycle operating between the boiler and condenser temperatures. B. Determine the actual efficiency of this Rankine cycle and compare it to the Carnot efficiency. C. When the Titanic was sinking, the Carpathia received the S.O.S. and immediately set course to attempt a rescue. The captain of the Carpathia ordered the hot water turned off in the passengers’ cabins (Lord, 1955). What effect do you expect this action had?

The net power (NOT TURBINE POWER) of the following steam power cycle is desired to be 25MW.Steam enters the turbine at 16 MPa, 450C, condenser at 10kPa pressure saturated liquid-steamIt enters as a mixture. Compressed liquid enters the pump at 9kPa at 35C and at 17MPacomes out. The inlet pressure to the boiler is 16.8MPa and 33C. The output from the boiler is 16.2MPa and 575C.The isentropic efficiency of the turbine is 90%, and that of the pump is 83%. Find the mass flow rate that will provide the required net power.
