Five cubic meters of water at 25°c and 1 bar have a mass of 4985 kg. a) list the values of two extensive and three intensive properties of the system, b) if the local gravity g for the system is 9.7 m/s2, evaluate the specific weight. (0.001m^3/kg, 4985 kg, 5 m^3, 9670 n/m^3)

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.
