Question
In 2010 the U.S. Center for Coastal and Ocean Mapping measured the deepest known point of the Earth's oceans in the Mariana Trench. It was $10994 \mathrm{~m}$ (36 $070 \mathrm{ft}$ ) deep, more than a mile taller than Mt. Everest. Compute the gauge pressure at that depth assuming the density of seawater is constant. [Hint: Use Table 12 -1.]
Step 1
The pressure at a certain depth in a fluid is given by the formula $P = \rho g h$, where $P$ is the pressure, $\rho$ is the density of the fluid, $g$ is the acceleration due to gravity, and $h$ is the depth below the surface of the fluid. Show more…

In 2010, the U.S. Center for Coastal and Ocean Mapping measured the deepest known point of the Earth's oceans in the Mariana Trench. It was 10994 m deep, more than a mile taller than Mt. Everest. Compute the gauge pressure at that depth, assuming the density of seawater is a constant 1.025 x 10^3 kg/m^3. Give your answer in kPa.
The greatest ocean depths on the Earth are found in the Marianas Trench, near the Philippines. Calculate the pressure due to the ocean, in atmospheres, at the bottom of this trench, given that its depth is 11.0 km and assuming the density of seawater is a constant 1.025 × 103 kg/m3 all the way down.
