Water flows in a constant-diameter pipe with the following conditions measured: at section (a) pa = 324 psi and 2a = 56.8ft; at section (b) pb = 29.7 psi and zb = 68.2 ft. is the flow from (a) to (b) or from (b) to (a)? explain.

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.
