Homework Statement
Water flowing out of a 16-mm diameter faucet fills a 2L bottle in 10s. At what distance below the faucet has the water stream narrowed to 10mm diameter?
Homework Equations
A1v1=A2v2 Q=vA
The Attempt at a Solution
edit: this is what I TRIED to do:(*note: i ignored some unit conversions at this time)
Q=2L/10s=2x10^-3 m^3/s.
v= Q/A = 2x10^-3 m^3/s / pi(5mm)^2 = 2.54x10^-5
x=vt = 2.54x10^-5 * 10s = 2.54*10^-4.
lol this is so wrong, it doesn't make any sense.
