Steam at a rate of 15lbm/s enters a turbine at 500 Psia, 800f and exits at 5 Psia. For a reversible, adiabatic process (iseentropic), what is the work out of the turbine in Btu/s and what is the entropy generation?© BrainMass Inc. brainmass.com October 9, 2019, 7:45 pm ad1c9bdddf
You need to determine the condition of the input steam. Use the accompanied references.
At 500 Psia and 800F, the inlet steam is superheated. Thus s1 = 1.6571 Btu/lbm R and h1 =1412.1 Btu/lbm
The solution determines the entropy generated in a steam turbine.
