Water is pumped into a storage tank from a well delivering 20. gallons of water in 30.0 seconds through a pipe of 1.00 in.^2 cross-sectional area. What is the average velocity of the water in the pipe as the water is pumped from the well?

My teacher explains the lesson only after assigning homework. I don't know anything.

Water flow rate, Q=20/30= 0.134*20/30 ft^3/sec.
Agai Q= A*V= (1/144)(V)
SoVelocity, V= (0.134*20/30)* 144 ft/Sec. Ans

You have a volumetric flow rate. You have a cross sectional area. The "height" of your cylinder is defined by your velocity. So, if you have the volume, and you have the area of the base and there is only one other variable in the equation for volume. . . stands to reason you might want to solve for that one variable. Personally, I would convert to a per second volumetric flow rate myself.
