1. The problem statement, all variables and given/known data The water behind a dam is 15.0m deep. A 4.00 cm diameter pipe is located 12.0 m down the dam. (density of water = 1.0x10^3 kg/m3 , 1.00atm = 1.0 x 10^5 Pa) Initially the pipe is closed. What is the pressure at the inlet to the pipe? 2. Relevant equations P_in=P_out + Dgh (D is density) 3. The attempt at a solution =1.0x10^5 Pa + 1.0x10^3kg/m^3 x 9.81m/s^2 x 12m =2.18 x 10^5 Pa??? Can someone tell how to set these problems up, or refer me to a website that explains it please?
