It is required to pump 45m^3/h of a hydrocarbon from a storage tank(at atmospheric pressure and 60 C) to distillation column. The liquid level in the tank will be 1.5m above the pump inlet. The suction line is 80 mm internal diameter commercial steel pipe (absolute roughness = 0.046 mm), 100 m long. Miscellaneous losses in the suction line are equivalent to 600 pipe diameters. The vapour pressure of the hydrocarbon at the pump suction is 25 kN/m2 (at 60 C). Determine whether this is a suitable pump arrangement if the NPSH required is 6 m. Density of fluid at 60 C =875 kg/m3 Viscosity of fluid: 1.45 mNs/m2
