Question
10) Water flowing through a garden hose of diameter 2.79 cm fills a 24.0-L bucket in 1.15 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 one-third the diameter of the hose, what is the speed of the water leaving the nozzle?
m/s
(a) Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.)
m/s
(b) Calculate the smaller section's pressure.
Pa
(a) Calculate the change in volume of 1.00 m3 of water carried from the surface to the bottom of the Pacific.
Explanation / Answer
(10)
formula for flow rate is
Q= A hose v hose
v hose = Q/A hose
= V/ t pi ( D/2)^2
= 24000 /1.15 (60) (pi ( 2.79/2 )^2
=56.92 cm/s
= 0.5692 m/s
(b)
Apply equation of continuity
A1 v1 = A2 v2
pi ( d/3)^2 v2 = pi d^2 ( 0.5692)
v2 = 0.5692 ( 9)
=5.12 m/s
