Question:

A geothermal power plant on the Raft river uses isobutane as the working fluid. The fluid enters the reversible adiabatic turbine at 320 F, 805 lbf/in 2 and the condenser exit condition is saturated liquid at 91 F. Isobutane has the properties Tc 734.65 R, Pc 537 lbf/in 2, Cpo 0.3974 Btu/lbm R 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.
