The pressure gauges are inserted at A and B in a vertical pipe converging water. The diameters at A and B are 150mm and 75mm respectively. The point B is 2.3m below point A. When rate of flow down the pipe is 0.021m³/s. The pressure at B is 117.72 KN/m² greater than at A. The losses in pipe between A and B are expressed as(KVa²/2g) where Va is velocity of A. Find the value of K. If the pressure gauges at A and B are replaced by tubes filled with water and connectef to a u-tube containing Hg(SHg=13.6) calculate the value of the reading manometer.

What is pipe roughness? A pump is located 5 m above the surface = 8170 M/m¹) 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 (/= 0.025). The discharge from the pump is 60 m of 20 cm diameter pipe (/= 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.
