Calculate Flow Rate: Find Water Velocity & Qty Collected

[physics337]

Homework Statement

I am trying to calculate the flow rate of the following setup. A bottle with water (density = 1000 kg/m^3) is on a lab stand, and has rubber tubing at the end of the bottle coming down to the benchtop. The top of the water is 17 inches above the benchtop. You insert a needle (with Inner diameter of 0.015 inches) into the tubing to start collecting water in a beaker for 30 seconds. What is the Flow Rate of the water that is being collected?

Homework Equations

The Attempt at a Solution

Velocity = √(2gh) =√(2*(386)*(17))=115 in/s
Q=Area* Velocity = ∏ (0.015/2)^2 * 115 = .02 in^3 / s
