Example 5-1 Carbon dioxide at 500°F and 210 psia enters a well- insulated turbine. The exit pressure is 5 psia and the mass flow rate is 22 lbm/s. If the work output is 850 hp, calculate the turbine efficiency. Solution: The actual work done by an adiabatic turbine is ( ) 1 2 W m h h = ± ± 1 Btu enthalpy(CO2, 500) 3749 lbm h T = = = − Solve for h2, 2 1 W h h m = ± ± ( ) 2 Btu 2544 h 850 hp 1 hp Btu Btu 3749 3776 lbm 3600 s lbm lbm 22 s 1 h h = = −

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
