Steam enters a turbine operating at a steady state at 8 mpa and 700 c. the mass flow rate of the steam is 135 kg/min. the steam exits the turbine as a saturated vapor at 18 kpa. the turbine produces 2.2 mw of power. ignoring potential and kinetic energy effects determine the: rate of heat transfer from the turbine to the environment in kw rate of entropy production in kw/k for an enlarged control volume that includes the turbine and enough of its surroundings that the heat transfer occurs at the ambient temperature of 25 °c. hint! assume that the environment acts as a reservoir. what does this imply relative to the temperature?

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.
