Summary

Pump Sizing for Trunkline from SP RDG to SPU AINTRODUCTIONTransfer pump design from SP Randegan to SPU ADESIGN METHODPump design is based on conventional equation for pump as per follows:1Suction Pressure = Tank Source Pressure + Inlet Static - Pressure loss (line loss , strainer , fittings, etc).2Net Pressure calculation (psia) = Suction Pressure - Vapor pressure3NPSH available (ft) = Net pressure / Density4Discharge pressure = Maximum Destination Pressure + Pressure loss (fittings, line loss,etc) + Elevation5Differential Pressure = Discharge Pressure - Suction Pressure6Safety factor = Differential Pressure x 10%7Required Differential Pressure = Differential Pressure + Safety Factor8Required Differential Head = Required Differential Pressure/ Density9Hydraulic Power = Required Differential Pressure x Rated Flow10Brake Power = Hydraulic Power / efficiency
