If you dive to 50 m below the surface of a lake,
a) what is the pressure due to the water alone?
b)What is the total or absolute pressure at that depth?
a) (water density)*g*(depth)
Your answer should be in N/m^2, equal to about 5 atmospheres)
b) [(water density)*g*(depth)] + atmospheric pressure
(1 atm more than part (a) )
