An adiabatic turbine (but not isentropic) has steam enter at a pressure of 200 psia, a temperature of 500 f and a velocity of 40 ft/s. the steam leaves at 20 psia and a temperature of 300 f an da velocity of 20 ft/s. the turbine is providing 100 horespower of work. answer the questions below but be careful to answer the correct question.
1. what is the actual mass flow in lbm/s through this turbine to three significant digits?
2. what is the maximum physically possible the turbine could supple in horsepower (hp) to three significant digits?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
