What is pipe roughness? A pump is located 5 m above the surface of a liquid (y = 8170 M/m³) in a closed tank. The pressure in the space above liquid surface is 35 Kpa. The suction line to the pump is 15 m of 15 cm diameter pipe (f= 0.025). The discharge from the pump is 60 m of 20 cm diameter pipe (f= 0.03). The pipe discharges in a submerged fashion to an open tank whose free liquid surface is 3 m lower than the liquid surface in the pressure tank. If pump puts 1.5 kW into the liquid, determine the flow rate and the pressure in the pipe on the suction side of the pump. Assume turbulent flow.
