Oil is pumped from a very large tank (z1 = 150 m) to another tank (z2 = 200 m), located higher and with a cross-sectional area of A = 0.02 m2. Both tanks are open to the atmosphere. The efficiency of the pump in the system is 78% and its power is 185 kW. Friction losses between two points are ΣF = 117.7 N.m / kg. Calculate the mass flow rate (M) of the oil in the pipe in kg / s (density of the oil ρ oil = 870 kg / m3; α = 1; g = 9.81 m / s2; gc = 1 kg.m / N.s2).
