Assume steam is the working fluid inside the Rankine cycle. At the turbine inlet, the steam is at 520 oC, 10 MPa. Assume the turbine isentropic efficiency is 85%, the pump is ideal, and the condenser exit is a saturated liquid.

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
