Its impeller diameter is DA = 6.0 cm, and its performance data when operating at n. A = 1725 rpm (?A = 180.6 rad/s) are shown in Table.The marketing research department is recommending that the company design a new product, namely, a larger pump (which we shall call pump B) that will be used to pump liquid refrigerant R-134a at room temperature. The pump is to be designed such that its best efficiency point occurs as close as possible to a volume flow rate of V. B = 2400 cm3 /s and at a net head of HB = 450 cm (of R-134a). The chief engineer (your boss) tells you to perform some preliminary analyses using pump scaling laws to determine if a geometrically scaled-up pump could be designed and built to meet the given requirements.
