Question

Provide a clear and complete solution as well as a diagram. 

A Rankine cycle has a steam throttle condition of 5Mpa and 420oC.  The turbine exhaust is 1 atm, find the cycle efficiency. 

At 5Mpa and 420oC: h= 3244.7, s= 6.7172

At 1 atm: sf= 1.3069, sfg = 6.7172   hf= 419.04, hfg = 2257,    v= 0.0010435m3/kg

 

A.  27.06%            B. 29.44%              C. 35.55%                  D. 28.41%
