 P: 4 1. The problem statement, all variables and given/known data A pump at ground level creates a gauge pressure of 102 kPa in the water line supplying an apartment building. The water leaves the tank into a pipe at a negligible speed. It travels up 10 m through the building and exits through a faucet. The cross-sectional area of the faucet is 2.0 cm^2. What is the Volume Flow Rate of the water leaving the faucet in cm^3/s? 2. Relevant equations Volume Flow Rate: Q=Av Bernoulli equation simplified: v = square root of: (Gauge Pressure - density of water*g*height)/(1/2 density) So put V into Q=Av and solve!? 3. The attempt at a solution I found it to be: 8 cm^3/m Where am I going wrong?
 Mentor P: 40,689 You solved for the speed v (in m/s). You need the volume flow rate, which is Av.
