Apump is used to transfer h2o from the surface of a lake into a tank where pressure is maintained at 350 kpa. the pump operates in steady flow with an efficiency of 0.6 and has an iniet volume flow rate of 0.5m^3/s. making good engineering assumptions, do the following: a) calculate the actual power required to drive the pump. b) determine the volume flow rate at the discharge of the pump. c) show this process on a t-s diagram including the saturation curve.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
