1.       A centrifugal pump running at 2950 rpm under test at peak efficiency gave the following results: Effective head H= 75m of water, rate of flow Q= 0.05 m3/s, overall efficiency h= 76%. A dynamically similar pump is to operate at a corresponding point of its characteristic when delivering 0.5 m3/s through a pipe 800m long and 1m diameter for which the friction coefficient f =0.05. The pipe discharges 90m above reservoir level. Determine the rotational speed at which the...
