Water flowing through a garden hose of diameter 2.72 cm fills a 25.0L bucket in 1.10 min.
(a) What is the speed of the water leaving the end of the hose?
m/s
(b) A nozzle is now attached to the end of the hose. If the nozzle diameter is onethird the diameter of the hose, what is the speed of the water leaving the nozzle?
m/s

you get 25L/1.1min
volume of lenght d of hose: diameter*length
= PI*(.0272dm)^2(L)
speed=L/time=25/(PI*.0272)^2 *1/1.10
speed is in dm/minute, so to change that to m/s, divide by 10, and multiply by 60.
