I don't know how to do this engineering problem. Need help! This is the complete problem. PLEASE DO NOT REJECT. I had other experts on bartleby help me with problems similar to this one. A regenerative vapor power cycle with two feedwater heaters, a closed one and an open one is shown in Figure 1. Steam enters the first turbine at 14 MPa, 520°C, and expands to 1.0 MPa. Some steam is extracted at 1.0 MPa and fed to the closed feedwater heater. The remainder expands through the second-stage turbine to 300 kPa, where an additional amount is extracted and fed into the open feedwater heater operating at 0.3 MPa. The steam, expanding through the third-stage, exits at the condenser pressure of 10 kPa. The two outputs from the feedwater both leave at 210°C. Assume the 12 MPa liquid in State 9 has an enthalpy approximately equal to saturated water at 210°C. The condensate exiting as saturated liquid at 1.0 MPa is trapped into the open feedwater heater and throttled into the open heater. Saturated liquid at 300 kPa leaves the open feedwater heater. Assume all pumps and turbine stages operate isentropically. Determine for the enthalpy of the fluid for each of the 11 states in Figure 1.
