Steam at 1 MPa, 582.8oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the temperature (oC) at the exit of the turbine. The final answer is 45.81 Solution given P1= 1MPa T1 =582.8oC and the given process is isentropic P2=0.01MPa steam expands i.e the volume increases the pressure decreases initial condition is supersaturated steam it changes to changes to saturated steam therefore from steam tables.. saturated steam at P2=0.01MPa the saturated temp= T2= exit temperature =45.80C.
