Document Summary
Cvg3116 - hydraulics: a 2km long, 0. 1m diameter pipe ( ) discharges water from a circular tank of 8m in diameter. The maximum and minimum operating water levels in the tank. Tutorial 3 are 120m and 105m meter above the pipe outlet, respectively. The entrance of the pipe is square edged and the pipe includes a gate valve that is fully open. Water is continually added to the tank at a rate of 0. 009cms. Determine the range of discharges and the time required for the water level to drop from the maximum to the minimum level inside the tank: a valve is placed at the downstream end of a 3km long pipeline. Water is initially flowing along the pipe at a mean velocity of 2. 5m/s. Also, sketch the variation in pressure at 1) the valve and 2) at the mid-point of the pipeline after the valve closure.
