Chapter 14, Problem 12CP

For each statement about cow cetrifugal the statement is true or false. and discuss your answer briefly:
(a) A centrifugal pump with radial blades has higher efficiency than the same pump with backward-inclined blades.
(b) A centrifugal pump with radial blades produces a larger pressure rise than the same pump with backward, or forward-inclined blades
over a wide range of
(c) A centrifugal pump with forward-inclined blades ii a good choice when one needs to provide a large pressure rise over a wide range of volume flow rates.
(d) A centrifugal pump with foird-inchned blades would most likely have less blades than a pump of the same size with backward-inclined or radial blades.
