We know that Q = pi * d * b * vf.
So that is directly proportional to d.
So that is directly proportional to d.

According to affinity law.
Flow or discharge is directly proportional to impeller diameter if the speed of the shaft is constant.
Flow or discharge is directly proportional to impeller diameter if the speed of the shaft is constant.

The correct answer is A,
q = d.
h =d^2.
p = d^3.
q = d.
h =d^2.
p = d^3.

Q = A.V.
A = π/4D2.
Q is directly proportional to d2.
A = π/4D2.
Q is directly proportional to d2.
