- A pump draws water from reservoir A and lifts it to reservoir B as shown in figure 4. Elev. of water at reservoir A is 10m.The loss of head from A to 1 is 3 times the velocity head in the 150mm pipe and the loss of head from 2 to B is 20 times the velocity head in the 100mm pipe. Compute the horsepower output of the pump and the pressure heads at 1 and 2 when the discharge is 200gpm.arrow_forwardOil with specific gravity of 0.88 is flowing in a 450 mm steel pipe with a velocity of 1.20 m/s.Find the rate of flow of oil.arrow_forwardExample Problem The fluid being pumped is oil with a specific gravity of 0.86. Calculate the energy delivered by the pump to the oil per unit weight of oil flowing in the system. Energy losses in the system are caused by check valve and friction losses as the fluid flows through the piping. The magnitude of such losses has been determined to be 1.86 N.m/N. Pump system. The volume flow rate through the pump shown in figure below is 0.014 m³/s.

- A horizontal 154 mm diameter pipe gradually reduces its section to 53 diameter, subsequently enlarging into 154 mm section. The pressure in the 154-mm pipe at a point just before entering the reducing section is 141 kPa and in the 53 mm section at the end of the reducer, the pressure is 73 kPa. If 627 mm of head is lost between the points where the pressure are known compute the rate of flow in L/s of water through the pipe.arrow_forward6. A Compressor of a compressed air system displaces air at 25 cubic meters per minute when the intake pressure is 101.4 kPa.
