(a) an adiabatic turbine expands steam from 500 °c and 3.5 mpa to 200 °c and 0.3 mpa at steady state. if the turbine generates 750 kw power (i.e., the rate of its shaft work is -750 kj/s), what is the mass flow rate of steam (kg/s) through the turbine? (b) if a breakdown of the thermal insulation around the turbine allows a heat loss of 60 kj per kg of steam (i.e., the rate of heat loss is 160 kj/sm), and the exiting steam 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? ignore changes of both kinetic energy and potential energy during your calculations.
