Superheated water vapor at 10 bars and 320 degrees c isallowed
to cool at constant volume until the temperature drops to150
degrees c. determine:
a) the final pressure
b) the final state (l, v-l, v), and the quality
(ifsaturated).

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
