In a purely turbulent flow driven entirely by pump work, if a circular pipe were replaced with one with half the inner diameter, the velocity through the pipe would be roughly... (a) x 0.25 the original velocity (b) x 0.5 the original velocity (c) x 0.7 the original velocity (d) x 1 the original velocity (e) x 1.4 the original velocity (f) x 2 the original velocity (g) x 4 the original velocity
