Chapter 8, Problem 872(choose chapter or problem)
Steam is usually accelerated in the nozzle of a turbine before it strikes the turbine blades. Steam enters an adiabatic nozzle at 7 MPa and 5008C with a velocity of 70 m/s and exits at 5 MPa and 4508C. Assuming the surroundings to be at 258C, determine (a) the exit velocity of the steam, (b) the isentropic efficiency, and (c) the exergy destroyed within the nozzle.
