Head & Piping Calculation Ref. Section WFU Flow Pipe Diam. Material Velocity Press - Loss Length Eq - Leng. Res.P.Loss Fric - Loss Tot.P.Loss

The document contains a table summarizing the calculation of head and piping for a plumbing system. It includes sections/legs of piping with information on flow rate, pipe diameter, material, velocity, pressure losses, length, equivalent length, friction loss, and total pressure loss. It then details the static pressure available, calculated pressure losses, minimum required pump head, and the water boosting pump selected with a head of 10m and flow of 1.0 l/s.
