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. Draw the approximate EGL and HGL.
