Homework Statement
Water travels through a pipe with a radius of 1 inch at a speed of 2 m/s. There is a nozzle at the end of the pipe with a radius of 1/4 inch. The pipe is horizontal and 2m above the ground. How far does the water travel in the air before hitting the ground?
r1 = 1 in.
r2 = 1/4 in.
V1 = 2 m/s
y = 2 m
Homework Equations
A1V1=A2V2
A = ∏r2
Δx = Vxt
The Attempt at a Solution
I found that A1 = 3.14 in.2 and A2 = .20 in.2
I plugged those in and found V2 = 31.4 m/s2.
Now I think I have to find t so I can work with Δx = Vxt but I'm not sure how to go about that or if that's even the direction I should be taking.
EDIT: I tried using kinematics, re-arranging V2 = V0^2 + 2aΔx. I plugged my values into -V0^2 / 2a = Δx and got -31.42 / 2(9.81) = 50.3 m
Would that be correct?
