Water Flow in pipes - urgent
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
