Question
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.

- p46,#15 with illustration and explanationarrow_forwardA fixed-mass system contains mass, m = 1.0 kg of air. A thermodynamic process occurs from state one to state two, where T₁ = 300 °K, P₁ = 100 kPa; T₂ = 2700 °K, P₂ = 204.9953251 kPa. Determine S₂ - S₁ = m (S₂-S₁) in kJ / °K. Note: You are required to assume constant specific heats in this problem, with Cpo = 1.004 kJ/(°K * kg); for air, the gas constant is R = 0.287 kJ/(°K * kg).arrow_forwardShow solution and diagrams.arrow_forward
