- Q1) Oil of specific gravity s.g = 0.8 is drawn into the pump, the pressure at A is -20 kpa and at B is 100 kpa. Calculate the power input of the pump if the discharge at B is 0.07 m'/s and the pipe diameter is 80 mm and h = 2.5 m as shown in Fig.1. Neglect friction losses. Take the efficiency of the pump 0.85 Fig.1arrow_forwardA pump with a volumetric displacement of 4 in^3/rev runs at 3600 rpm and produces 1500 psi. The actual flow rate is 59 gpm.

If the pressure difference between the two ends of the joint is equal to C (mm) of mercury, calculate the average velocity at the inlet and outlet sections, and find the volumetric flow rate if the loss is small that can be neglected.arrow_forward8.) A liquid having a sp.gr. of 20 is flowing in a 50 mm diameter pipe. The total head at a given point was found to be 17.5 Joule per Newton. The elevation of the pipe above the datum is 3 m and the pressure in the pipe is 65.6 kPa. Compute the velocity of flow and the horsepower in the stream at that point.

The mercury manometer shows a reading of 900 mm.arrow_forwardShow all problem solution's steps. Direct formula substitution solutions will have NO CREDIT POINTS. 1.A 50 mm Venturi meter (C = 0.96) is installed in a 100 mm diameter horizontal pipe carrying oil having a specific gravity of 0.82. If the recorded actual flow in the Venturi meter was 15 liters per second, what could have been the deflection of water in the differential manometer connected between the inlet and the throat? Determine the headloss in the Venturi meter. A 75 mm diameter fire hose discharges water through a nozzle having a jet diameter of 25 mm. The lost head in the nozzle is 25% of the velocity head in the jet. If the pressure at the base of the nozzle is 625 KPa: compute the discharge in m3/min; the maximum horizontal range to which the stream can be thrown; the maximum vertical reach, and the diameter of the jet at a point two-third of the maximum vertical reach from the tip of the nozzle.
