A 900 mm steel pipe 1000 m long supplies water to a small power plant. To protect against instantaneous closure of a valve at the plant, a simple surge tank 2 m in diameter is fitted at a point where the centre line of the pipe is 40 m below the water surface in the reservoir. The steady state discharge is 5 m/s. The surge tank is not to overflow. By neglecting the friction and minor losses, find (1) the height, z, required for the surge tank. maximum value of y, and state the reason Describe how will the height you obtained be affected if energy losses in the pipe are considered A 900 mm steel pipe 1000 m long supplies water to a small power plant.
