A geothermal power plant on the Raft river uses isobutane as the working fluid. The fluid enters the reversible adiabatic turbine, as shown in Fig. P13.42, at 160C, 5.475 MPa and the condenser exit condition is saturated liquid at 33C. Isobutane has the properties Tc 408.14 K, Pc 3.65 MPa, CP01.664 kJ/kg K and ratio of specific heats k 1.094 with a molecular weight as 58.124. Find the specific turbine work and the specific pump work.
