Steam enters the turbine of a simple vapor power plant with a pressure of 12 MPa and a temperature of 600°C and expands adiabatically to condenser pressure, p. Saturated liquid exits the condenser at pressure p. The isentropic efficiency of both the turbine and the pump is 84%.
a. For p = 30 kPa, determine the turbine exit quality and the cycle thermal efficiency.
b. Plot the quantities of part (a) versus p ranging from 6 kPa to 100 kPa.
Problem 1

I also need help with part d. The figure below provides steady-state operating data for a cogeneration cycle that generates electricity and provides heat for campus buildings. Steam at 1.5 MPa, 280°C, enters a two-stage turbine with a mass flow rate of m1 = 2 kg/s. A fraction of the total flow, y = 0.15, is extracted between the two stages at 0.2 MPa to provide for building heating, and the remainder expands through the second stage to the condenser pressure of 0.1 bar. Condensate returns from the campus buildings at 0.1 MPa, 60°C and passes through a trap into the condenser, where it is reunited with the main feedwater flow.
