Homework Statement
The photo below shows a stream of water in steady flow from a kitchen faucet. At the faucet, the diameter of the stream is 0.960 cm. The stream fills a 0.125cm3 container in 16.3 s. Find the diameter of the stream 13.0 cm below the opening of the faucet.
Homework Equations
The Attempt at a Solution
The official solution says to take P1 = P2. Why is this? Isn't the pressure at the bottom of the column greater than the pressure at the top? I'm not quite grasping an explanation that says "the pressure at the top and at the bottom of the stream is the same: atmospheric pressure." Wouldn't a pressure gauge inside the stream near the top register a different value than one near the bottom?
Thank you!
