You are right @Shivanand. Thanks.

Power develop by turbine given by.

P = η * ρ * g * h * Q.

H proportional to H3/2.

Ref: RS Khurmi Gupta.

I think it's inversely proportional.

P=pQgH.

Here q is proportional to h^1/2 as Q=av here v=2gh^1/2.

The correct Answer is C.

It is given for centrifugal pumps.

(P1/P2)=(D1/D2)^3 and H1/H2=(D/D2)^2
Now equate the above equation.

Pu = P/H^3/2.

Hence, P = Pu* H^3/2.
