77 as the oil pump is drawing 35 kW of electricity while pumping oil to 860 kg/m3 = 0.1 m3/s rate, outbound, inbound diameter 8 cm and 12 cm pipe.A pump is a pump in the indicated rate. Increasing the pressure of the oil in the pump is measured and specified performance motors. Mechanical performance of the pump will be set.The assumption of constant flow and 1 Compressor 2 comparisons across pump. ...The density of the oil properties, was 860 kg/m3 = 0.The total mechanical energy and analysis of liquid flow is the sum of the potential and kinetic energy. Energy and mass are expressed per unit = 2/2 mech to monitor the performance of the machinery of the pump, we need to know the increase in mechanical energy of the liquid flowing through the pump which is.Liquid emech = m (emech out – emech) = m (PV) 2/2 2 v2 (PV) 1-v12/2) = ((((P1 P2) (2-v12 V2)When m = = V/V, and there is no change in the potential energy of the flow.V1 = volume/A1 = 0.1 m3/sec)/(0.08 m) 2/4) = 19.9 m/s.A2 = V/2 = 0.1 m3/sec)/(0.12 m) 2/4) = m/s.Electric water pump, the boss can strive to become wpump =.= Emech. liquids (0.01 m3/s) (400 (860kg KN/m2/m3) * (8.84 sq meters/second) 2-NN19D9m/S2)/2 * (1kn/M/S2 1000kg.)
