Pressure in a column of water

  • #1

Homework Statement


I feel like I'm doing something seriously wrong here.:uhh:

How tall must a column of water be to generate a pressure of 100mmHg?

Homework Equations


P = pgh, I think, is the only necessary equation.


The Attempt at a Solution



So..... 100mmHg = 1 kg/m3 * 9.81 m/s2 * 1mmHg/133.322Pa * h

h = 1.36 km?

Seems a bit much, don't ya think?
