Water vapor enters a turbine operating at steady state at 500°c, 3 bar, with a velocity of 200 m/s, and expands adiabatically to the exit, where it is saturated vapor at 1.0 bar, with a velocity of 150 m/s and a volumetric flow rate of 20 m3/s. find mass flow rate through the turbine. determine the power developed by the turbine, in kw. neglect potential energy changes, heat losses.

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
