It is known that the head of a centrifugal pump slightly increases when the roughnessincreases on the outer surface of the impeller of a centrifugal pump.The authors report the results about a volute pump that by measuring the velocitydistribution in the axial direction in the inlet of the casing. (namely, immediately afterthe water ran out the impeller.)We examined the relation between the velocity distribution and the head rise.
