1. The problem statement, all variables and given/known data The main water line enters a house on the first floor. The line has a gauge pressure of 1.70 X 10^5 Pa. (a) A faucet on the second floor, 5.2 m above the first floor, is turned off. What is the gauge pressure at this faucet? Pa (b) How high above the water main could a faucet be before no water would flow from it, even if the faucet were open? 2. Relevant equations P(gauge)=[tex]\rho[/tex]gh Pabs = Patm + Pgauge Pabs = 1.01 X 10^5Pa + [tex]\rho[/tex]gh density of water = 1000kg/m^3 3. The attempt at a solution i tried to use both of these equations but it didn't work. do i need to use 1.70 X 10^5Pa when solving the problem? I tried the first equation and got 51012Pa (1000 X 9.81 X 5.2) i tried using the second one and got the wrong answer too. then i tried to find the density at the closed water fountain.. but i wasn't even sure how to use that information. which equation should i use to solve a? i'm sure i can solve b after finding this.
