Consider a pipe in which water flows with a velocity of 0.5 m/s and is at a temperature 20 c. find the distances from the entrance at which the velocity and thermal layers meet.

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.
