i know that Av=volume flow rate

for this problem the flow rate is 0.008m^3/s. Do i divide by the radius^2 to get velocity or is there someother equation im supposed to be using

- physics -
**drwls**, Sunday, November 11, 2007 at 8:22amVolume flow rate Q (which is 0.0080 m^3/s in your case) is always equal to the product of fluid velocity and the cross sectional area of the flow. In this case that area is pi*r^2, where r is the pipe radius.

Therefore V = Q/(pi r^2)
