Chapter 4, Problem 4.99(choose chapter or problem)
Figure P4.99 shows a turbine-driven pump that provides water to a mixing chamber located 25 m higher than the pump. Steady-state operating data for the turbine and pump are labeled on the figure. Heat transfer from the water to its surroundings occurs at a rate of 2 kW. For the turbine, heat transfer with the surroundings and potential energy effects are negligible. Kinetic energy effects at all numbered states can be ignored. Determine
(a) the power required by the pump, in kW, to supply water to the inlet of the mixing chamber.
(b) the mass flow rate of steam, in kg/s, that flows through the turbine.
