## Homework Statement

Water is flowing through a pipe of radius 4 cm with a speed of 15 m/s The pipe increases 3 M in height with no change in pressure or speed. What is the radius of the pipe in cm at this new height?

## Homework Equations

P1+1/2[tex]\rho[/tex]V1

^{2}+[tex]\rho[/tex]gY1=P2+1/2[tex]\rho[/tex]V2

^{2}+[tex]\rho[/tex]gY2

The rho's are not exponents they just appeared like that.

A1V1=Constant

## The Attempt at a Solution

I know since I have the radius and speed I can find the Flow rate using the continuity equation. (.04)

^{2}[tex]\pi[/tex](15 M/s) = .075 m

^{3}/s

The Pi should not be an exponent either. Sorry

Since I have the flow rate I do not know what I should do to relate the rise of 3M in height with Bernoulli's equation. I know since they have the same speed density and pressure; most of the factors will cancel out. Am I missing an equation that could help me out??
