Question
Transcribed Image Text:1. A cylindrical vessel 4-ft in diameter and 6-ft high has a round-edged orifice 2" in
diameter in the bottom. The coefficient of discharge of the orifice is 0.95. If the vessel is
filled with water, how long will it take to lower the water surface to a height of 4 ft?

- Three new cast-iron pipes connected in series have diameters of 30 cm, 25 cm, and 20 cm, each being 200 m long. The largest pipe leads from a reservoir and the smallest discharges into the air. Determine the total head loss when the discharge is 100 liters per second. What must be the elevation of the outlet end of the pipe with respect to the water surface elevation in the reservoir? n for Manning’s equation is 0.011 and the minor head loss due to contraction is 30% of the velocity head on the pipe after the change in cross in the direction of flow.

- A cylindrical tank of water is 20 m in diameter and 3.5 m tall. There is a 1.0 cm diameter hole at the bottom from which water is leaking. A feeder pipe at the top of the tank, 4.0 m above the ground delivers water at a rate of 0.02 m/min. Ir the tank is initially half full, tal what is the water flow rate in m^3/sec from the top feeder pipe? (bi what is the pressure at the bottom of the tank?
