Which one of the following is a WRONG statement?
(A) The head generated by a centrifugal pump at zero discharge is the 'shutoff head'.
(B) To avoid cavitation in centrifugal pumps, the net positive suction head should be more than the theoretical atmospheric pressure.
(C) According to the affinity laws of centrifugal pumps, the head varies with the square of the impeller speed.
(D) Most of the turbine pumps have operational characteristics closer to those of the centrifugal pumps than the propeller pumps.
