The correct formula is WQH/75.

Plese tell me if I'm wrong.

Agree @Shahzeb.

It is Wqh/75.

Yes, it should be 75 in place of 15.

w = unit wt of water in KN/cum.
Q = Discharge in cum/sec.
H = total head.
Then, required H.P. = wQH/0.735.

Hers, H.P = (wQH)/(0.735*efficiency of pump).

Water horse power= w*Q*H/75.
Break horse power= w*Q*H/ efficiency.

Yeah, it's WQH/75.

Not 15.

No it Should be 75 instead of 15.
