Step 1
This problem involves pressure in fluids, specifically the pressure at a depth within a fluid. The key concept is that the pressure at a depth in a fluid is equal to the atmospheric pressure plus the pressure due to the weight of the fluid above that depth. Show more…

How deep under the surface of a lake would the pressure be triple that at the surface? ( 1 atm = 1.01 x 105 Pa) (water density= 1e3 kg/m^3)

Calculate the absolute pressure at a depth of 4.00 m due to water in a pond. NOTE: 1 atm = 1.013x10^5 Pa, g = 9.80 m/s^2, and the water is pure fresh water.

Pressure under Water The pressure $p$ experienced by a diver under water is related to the diver's depth $d$ by an equation of the form $p=k d+1(k$ a constant). When $d=0$ meters, the pressure is 1 atmosphere. The pressure at 100 meters is 10.94 atmospheres. Find the pressure at 50 meters.
