Air pressure at the surface of a fresh water lake near sea level is about 10^5 N/m2. At approximately what depth below the surface does a diver experience a pressure of 3.0 e5 N/m2?

1 answer

3e5 N/m2 = 3 bar
Sea level is 1 bar
Pressure increases 1 bar for every 10.06 m so to go from 1 bar to 3 bar would require 3*10.06 m = ?
