Note that there are two sets of affinity laws:.
Affinity laws for a specific centrifugal pump - to approximate head, capacity and power curves for different motor speeds and /or different diameter of impellers.
Affinity laws for a family of geometrically similar centrifugal pumps - to approximate head, capacity and power curves for different motor speeds and /or different diameter of impellers.

According to the affinity laws horsepower is directly proportional to the fifth power of impeller diameter or cube of rpm, so this answer is not right.
