The curve A in the to the right is headcapacity relationship

The curve A in the to the right is head-capacity relationship of a single centrifugal capacity Select the head-capacity relationship obtained when two such pumps put together in parallel A B C None of the above A centrifugal pump, with pump equation 606-50Q^2, is considered for a pipe with pipe equation 300 + Q^2; what will be flow rate through this system if this used 2 m^3/s 4 m^3/s 5 m^3/s 6 m^3/s The procedure of fitting straight line to a given data set is known as linear True False The maximum value that correlation coefficient can assume is 0 0.5 1 9

Solution

1.5) answer is B

EXPLANATION- If two centrifugal pumps are connected in parallel and the head kept constant then the flowrate doubles compared to a single centrifygal pump. Consider the flow rate at curve B. It is double that of curve A.
