Question

A hollow pipe is submerged in a stream of water so that the length of the pipe is parallel to the velocity of the water. If the water speed doubles and the cross-sectional area of the pipe triples, what happens to the volume flow rate of the water passing through the pipe?

A) The volume flow rate does not change.
B)The volume flow rate increases by a factor of 2.
C)The volume flow rate increases by a factor of 3.
D)The volume flow rate increases by a factor of 6.

Answer 1

D)The volume flow rate increases by a factor of 6

Step-by-step explanation:

Volume = Area * Velocity

Velocity is doubled V = 2

Area is tripled A = 3

Volume 3 * 2 = 6m^3/s
