Figure Q1 shows an internal piping system of a building. The pipe is uPVC of total length 35 m. The minor loss coefficients are as shown in the figure. The flow velocity in the pipe is designed to be 1.0 m/s and the residual pressure head at appliance X must be at least 0.8m. Determine the required pipe diameter using Darcy Weisbach formula.
