An open tank contains water at the bottom for a depth of 6 ft and 3 ft of oil ( 0.75) above water. water is discharged from the tank through a 4-inch diameter orifice located 2 ft above the bottom. assuming steady liquid levels and no losses, determine the volume flow rate through the orifice.

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.
