The absolute pressure below the surface of a freshwater lake is 3.51 x 10^5 pa. at what depth does this pressure occur? assume that atmospheric pressure is 1.01 x 10^5 pa. and the density of the water is 1.00 x 10^3 kg/m^3

The general formula for absolute pressure is:



Where: = Absolute pressure
               = atmospheric pressure
             r = density
             g =
             h = depth

We can use this formula to derive our formula for h:

      transpose atmospheric pressure
 =       transpose r and g

-
-------------------------      = h
         rg

Now let us input our given into our new formula:

3.52 x   - 1.01 x
----------------------------------------              = h
1.00 x  x 9.8
