A trapezoidal flume carries water. It has a base of 30 cm, a top of 60 cm, and sloped wall lengths of 25 cm. The water flowing in the flume has a vertical depth of 16 cm with a wetted perimeter of 70 cm. The flume has a Manning roughness coefficient of 0.02 and a slope of 10 m/km. The total flume area is 900 cm2, while the flow area is 672 cm2. Using the Manning equation for open channel flow, what is most nearly the velocity in the flume in m/s

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.
