Homework Statement
water in main pipe at the street level is at a gauge pressure of 170 KPa and is moving with neglibible speed. A pipe connected to the main pipe is used to deliver the water to kitchen located on the third floor of a building, at a 15-m height from the street level. what is the maximum possible velocity with which the water can emerge from an open kitchen faucet?
Homework Equations
p1+1/2 rho G v^2+rho G H = p2 + 1/2 rho G v^2 + rho G H
The Attempt at a Solution
i have the equation p1=p2+1/2(rho)GV^2+(rho)G H
since p1 speed is negligible and height is 0. I am not sure abount what p2 is. is it the atmosphere pressure?
the answer is 6.8m/s, but i can't get the answer. pls help
