**Water Flow in pipes - urgent**

## Homework Statement

Water is flowing through a pipe whose radius is 0.04m with a speed of 15m/s. The same pipe goes up to the second floor of the building, 3m higher, and the pressure remains unchanged. What is the radius of the pipe on the second floor?

EDIT: NVM, SOLVED!

Here's the solution anyways

1/2(15^2) + 9.8 * 0 = 1/2(v^2) + 3 * 9.8

solve for v

then put v into (.04^2 * pi) * 15 = (r^2 * pi) * v

pi cancels

and tada

u get r = 0.043m
