13. A pump draws water from a sump through a vertical 6" pipe. The pump has a horizontal discharge 4" in diameter that is 10.6 ft above the water level in the sump. While pumping 1.25 cfs, gages near the pump at entrance and discharge read -4.6 psi and +25.6 psi, respectively. The discharge gage is 3.0 ft above the suction gage. Compute the horsepower output of the pump and the head lost in the 6" suction pipe.

please do step by step The pipe in figure discharges water from an upper tank to a lower tank as shown. The pipe consists of 500-ft long of a 6-in diameter wrought iron (f = 0.016) Neglect minor losses.
4.2.11. A pump is needed to convey 8 cfs of water at 68°F through a 130-ft-long horizontal, ductile iron pipeline to a pressurized tank. The pump and pipeline are installed at an elevation of 10 ft, the water surface elevation in the receiving tank is 20 ft, and the pressure at the top of the tank is 32.3 psi. The pipe has a 15-in.-diameter on the suction side of the pump and a 12-in.-diameter on the discharge side of the pump. If the pump delivers 111 ft of head, determine the pressure head on the discharge side of the pump (in psi) and whether cavitation is a concern on the suction side of the pump? Sketch the system and draw the HGL and EGL.
