Q (m/s) H (m) n (%) 71 Example 3.8 A centrifugal pump has an impeller diameter 0.50 m and its characteristics are as follows: 0 0.10 0.15 0.20 0.25 0.30 40 37.5 33.0 27.5 20.0 12.0 0 73 82 81 48 Draw the characteristics of a geometrically similar pump having an impeller diameter of 0.562 m and running at the same speed. If the two pumps operate against a system which includes a static lift of 10 m and is such that the smaller pump delivers 0.22 m3/s, establish the operating point of the larger pump and the operating efficiencies of both pumps. Show on your graph some lines connecting the corresponding points on the two characteristics.
