Consider a flat plate of width 0.6 m and length 1.3 m that is maintained at a temperature of 40◦c. water at 20◦c flows across the top of the plate in parallel flow at a velocity of 3 m/s. determine the rate of convection heat transfer and drag force on the plate. what if the flow was fully turbulent over the plate?

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.
