An 8-in centrifugal pump with characteristic curves shown on the attached page is placed in an 8-indiameter steel pipeline with a total length of 3,000 ft. The pump lifts water from a reservoir at El. 65’ to a reservoir at El. 100'. Assume f=0.02. Determine pump operating point for pump Determine pump efficiency and required power input • Estimate acceptable pump flow range Suggest why pump may be designed to initially operate to the right of BEP O Suggest a reason that pump must operate at a lower speed The manufacturer claims to have a similar 10-in pump. What is this pump's specific speed if the claim is true?
