The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz⁢= 5 m higher than the pump, where m˙=50 kg/s. 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 magnitude of the pump power, in kW.(b) the mass flow rate of steam, in kg/s, that flows through the turbine.
