Steam at 200 psia and 600 degrees F [state 1] enters a turbine through a 3 inch diameter pipe with a velocity of 10 ft/s. The exhaust from the turbine is carried through a 10 inch diameter pipe and is at 5 psia and 200 degrees F [state 2]. What is the power output of the turbine? H1= 1322.6 Btu/lbm v1=3.058 (ft)^3/lbm H2= 1148.6 Btu/lbm v2=78.14 (ft)^3/lbm
