26. The Carnot vapor power cycle see figure 5.15 gives the schematic of a vapor power plant in which water steadily circulates through the four components shown. The water flows through the boiler and condenser at constant pressure and through the turbine and pump adiabatically. Kinetic and potential energy effects can be ignored. Process data follow Hote, 304 Boler NE TC Corte Fig. 5.15 Carnot vapor power cycle On OM a. Process 4-1: Constant pressure at 2 MPa from saturated liquid to saturated vapor b. Process 2-3: Constant pressure at 20 kPa from X - 80% to x = 30% 1. Find enthalpy at each sate ii. Find T. & Tin Kelvin lii. Find iv. Apply equation 5.13 expressed on a time-rate basis, determine if the cycle is internally reversible, irreversible or impossible. Refer to 5.11 Clausius inequality and note 0.-9& Cauca v. Determine the thermal efficiency using eq 5.4 expressed on a time-rate basis and steam table data. vi. Compare the results of part(b) with the Camot efficiency calculated using equation 5.9 with the boiler and condenser temperatures and comment.
