A pump draws water from a 20 cm diam suction pipe and discharges through a 15 cm diam pipe in which the velocity is 3.60 m/s. The pressure is – 34. 465 kPa at A in the suction pipe. The 15 cm diam pipe discharges horizontally into air at C inclined at 45 degrees. Find the maximum height and range that the water can reach if B is 1.8 m. above A and 20 hp is delivered to the pump? Assume that the pump operates at 80 % efficiency and that the frictional loss in the pipe between A and C is 3 m

The flow is opened to the atmosphere at point D which is fed by a very wide reservoir that has a water surface elevation of (5+) meters as shown in the figure given below. Elevation of the horizontal axis BC is 1 meter. At sections AB the diameter of the pipe is (0.2+- meters and CD the diameter of the 100 pipe is (0.3+: meters. The flow is ideal (inviscid) and absolute atmosphere pressure is 9.81 N/cm?. Considering the pipe's diameter is (0.15+; m at section BC, find the discharges and the 100 а. velocities of the flow at other sections (AE, EB, BC, CF, FD). Draw the energy and hydraulic grade lines of the system. b. Assuming the system discharge is constant and has the value you have found in (a), calculate the minimum pipe diameter that the section BC can take and draw the energy and hydraulic grade lines of this situation.

A steel pipe is used to drain water from a reservoir that is 50 m above the datum, and water is discharged into the air at the elevation of the datum. The pipe is 1500 m long and 450 mm diameter and 50 mm wall thickness. A valve is installed at the downstream end of the pipe allows a flow rate of 0.71 m³/s. The valve was completely closed in 1.4 sec. Calculate maximum hammer pressure at the valve. The pipe is longitudinally anchored. Eb = 2.1×10° N/m², Ec=1.9×10¹¹ N/m².
