A centrifugal pump transports gasoline from tank A to tank B (Fig.). The level of gasoline in the tank is AN = 20 m. Determine the suction height of the pump, the discharge height and the pressure measured at the outlet section of the pump. Initial data: gasoline consumption Q = 6.13•10-3 m3/s, pipeline diameter d = 0.05 m; p = 810 kg/m3; v = 2.7•10-6 m2/s, pressure loss coefficients due to local resistance: input Ein = 0.5; tap Ecr = 0.17; valves E = 2; output Ev = 1; l1 = 6.5 m; l2 = 116 m.
