Document Summary
Tutorial 3 - solutions: a 2km long, 0. 1m diameter pipe with discharges water from a circular tank of 8m in diameter. The maximum and minimum operating water levels in the tank 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. 0009cms. 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. Solution: we write the general differential equation for unsteady flow between reservoirs: Substitute the equations found in iii into the equation found in i. Cvg3116 - hydraulics: 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.
