1. The problem statement, all variables and given/known data In a tank full of water, the pressure on a surface 2 meters below the water level is 1.5 kPa. What is the pressure on a surface 6 meters below the water level? 2. Relevant equations Isn't this impossible? The equation given is P=hdg. (height of water column x density x 9.8m/s/s) and the density of water is 1. 3. The attempt at a solution So by that equation, the pressure 2 meters below would be P=2m x 1 x 9.8m/s/s = 19.6 kPa and the pressure 6 meters below the surface would be P= 6m x 1 x 9.8m/s/s = 58.8 kPa Am I misunderstanding something here? Thank you in advance!
