Water at 20°c flows through an inclined 8-cm-diameter pipe. at sections a and b, pa=260 kpa, va=3.2 ms, za=9.1 m, while pb=186 kpa, vb=3.2 m/s, and zb= 24.5 m. which way is the flow going? what is the head loss in meters hint: assume the flow direction, write the energy equation and see if the calculated head loss is positive.

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.
