The data of Prob. 11.31 correspond to a pump speed of 1200 r/min. (Were you able to solve Prob. 11.31 without this knowledge?)
(a) Estimate the diameter of the impeller [HINT: See Prob. 11.24 for a clue.].
(b) Using your estimate from part (a), calculate the BEP parameters rs Q*, *H, and *P C C C and compare with Eq. (11.27).
(c) For what speed of this pump would the BEP head be 280 ft?
