# Experiment for measuring flow rate vs diameter

I am trying to establish the relationship between the diameter size of a pipe and the flow rate water. The main idea for my experiment would be to run water through pipes of varying diameter and measure the flow rate.

I was thinking of the following setup:

Water tap $$>$$ pipe $$>$$ Measuring device (like venturi meter)

In other words, the water would flow from the tap into the pipe. Then, I will try to measure the flow rate using something like a venturi meter. Or, I was also thinking of dropping something like a small particle on one end of the pipe and measure its velocity on the other end.

Would this setup be enough to complete the experiment?

• Thanks for your reply! Just to confirm, The flow rate would simply be equal to $\frac{(Volume of bucket)}{time(in seconds)}$ right? Also, its fine if the pipe cross-section isn't completely filled with water right? – NoLand'sMan Sep 14 '19 at 7:41
