A1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. the temperature and pressure are 100°c and 101.33 kpa. from a water line at a constant temperature of 70°c and a constant pres- sure somewhat above 101.33 kpa, 750 kg of liquid is bled into the tank. if the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?
