An adiabatic turbine expands steam from 500 °c, 3.5 mpa to 200 °c, 0.3 mpa. if the turbine generates 750 kw, what is the flow rate of steam through the turbine? b) if a breakdown in the thermal insulation around the turbine allows a heat loss of 60 kj per kg of steam, and the exiting stream is at 150 °c and 0.3 mpa, what will be the power developed by the turbine if the inlet steam conditions and flow rate are unchanged?

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?

Steam flows steadily into a turbine with a mass flow rate of 26 kg/s and a negligible velocity at 6 mpa and 600°c. the steam leaves the turbine at 0.5 mpa and 200°c with a velocity of 180 m/s. the rate of work done by the steam in the turbine is measured to be 20 mw. if the elevation change between the turbine inlet and exit is negligible, determine: (a) the rate of heat transfer associated with this process.

Steam enters a turbine operating at steady state at p1=6 mpa, t1 = 600°c with a mass flow rate of 335 kg/min and exits as saturated vapor at p2=20 kpa, producing power of 5.36 mw. kinetic and potential energy effects can be ignored. heat transfer occurs from the turbine to its surroundings which are at to = 30°c determine the magnitude of the rate of heat transfer, in kw, and the rate of entropy production, in kw/k, within an enlarged control volume that includes the turbine and enough of its surroundings for the heat transfer to occur at to=30°c.
