Q= π*D*v*b and v=πdN/60.
So the right answer is proportional to d^2.
So the right answer is proportional to d^2.

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

Q/(N*D^3).
So, the correct answer is directly proportional to D^3.
So, the correct answer is directly proportional to D^3.

Q=(pi)DbV.
D=Diameter of impeller.
B =Width.
V= Velocity of flow.
D=Diameter of impeller.
B =Width.
V= Velocity of flow.
