Apower company desires to use groundwater from a hot spring to power a heat engine. if the groundwater is at 95 deg c and the atmosphere is at 20 deg c, what is the maximum power output for a mass flow of 0.2 kg/s? assume the water is cooled to atmospheric temperature.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
