gas with Cp* = (7/2)R.

4-29. Throughout Chapters 3 and 4, we have assumed that potential and kinetic energy are negligible in standard chemical process equipment. This prob- lem tests how valid these approximations are for a turbine. Steam at 14 bar and 300C enters a tur- bine through a 5 cm diameter pipe at a velocity of 2.5m/s. The exhaust exits via a 20 cm diameter pipe that is located 1.5 m below the inlet pipe. The exhaust is saturated steam at 0.9 bar.Assume steady- state, adiabatic operation, but assume nothing else about various contributions to the energy balance. A. Determine the mass flow rate entering the turbine. B. Determine the power output from the turbine. C. Determine the efficiency of the turbine.
