The same fluid flows through four different branching pipes. It enters each pipe from the left with the same speed, v0, and flows to the right. Assume that the fluid fills the pipes everywhere completely. You can also assume that all of these pipes are in the horizontal plane and that you are looking at them from above, so that there are no differences in height anywhere among the pipe branches. Finally, you can ignore viscosity. Which fluid speed is the largest?
All four speeds are the same.
a. v1
b. v4
c. v2
d. v3
