Apower plant produces electrical power by running water through a turbine. the plant produces 33 kw by utilizing a stream of water that drops 40 m from a reservoir to the turbine and flows at a rate of 150 kg/s. what is the efficiency of the turbine‐generator?

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
