WebAnswer (1 of 22): Doubling the diameter is effectively doubling the radius; r = ½(diameter). Area of a circle is a function of square of the radius. f(r) = πr² When radius is doubled; … Web8. The flow rate is the average velocity times the area. If the velocity was constant, you would get a flow rate that scaled with r 2 (the area). But the velocity goes up for larger pipes - in fact, velocity scales with the square of the radius. And the product of these two squares gives us the 4th power relationship.
