Question:

Steam enters an adiabatic turbine, operating at steady state, with a flow rate of 10 kg/s at 1000 kPa, 400°C and leaves at 40°C with a quality of 0.9 (90%). Neglecting changes in ke and pe, determine.
(a) The pressure (in kPa) at the turbine exit.
(b) The turbine output in MW.
(c) The rate of entropy generation.
