When you turn on a faucet and the water streams straight down, you can observe that the diameter of the water stream decreases as the water falls (try it!). This isn't entirely due to surface tension. Suppose the water emerges from a 1.75 cm diameter faucet at a speed 0.6 m/s.

  1. What is the flow rate?
  2. What is the diameter of the water stream 20 cm below the faucet?

A faucet is turned on with a flow rate that allows the fluid to flow smoothly (i.e. laminar flow). As the fluid falls the fluid accelerates due to gravity and the diameter of the fluid stream decreases. The initial speed, at the faucet, is 9 cm/s, and the inital diameter of the fluid stream is 0.7 cm. What is the diameter of the fluid stream 4.3 cm below the faucet.     (Reminder: vf2 = vi2 + 2g(Δy) (using positive direction, as...
