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?
