A barrel will rupture when the gauge pressure inside reaches 345 kPa. A vertical pipe is attached to the lower end of the barrel. The barrel and pipe are filled with oil, density of 1200 kg/m3. How long can the pipe be if the barrel is not to rupture?

Answer 1

pressure=h*1.2*9.8 kpa
set that equal to 345kpa, solve for h in meters
