A centrifugal pump delivers water through a 40-cm-diameter, 1,000-m-long commercial steel pipe from reservoir A to B with EA = 920.5 m and £8 = 935.5 m. Friction losses vary according to the Moody diagram (alternatively, the Swamee-Jain equation, 3.24a). Neglecting minor losses, determine the discharge in the pump-pipeline system using the pump performance characteristics in the following table.
