The formula to calculate Pressure (P) at a certain depth is:
\[ \text{P} = \text{d} \times \text{p} \times \text{g} \]
Where:
Pressure depth is defined as the total pressure acting on an object that is submerged in a fluid at a certain depth. The pressure is caused by the force of gravity acting on the fluid. As depth increases, the pressure on an object also increases.
Pressure and depth are directly correlated. As depth increases, pressure increases linearly. The pressure increases due to the weight of the fluid above the object, which exerts a force on the object as it goes deeper into the fluid.
Let's consider an example:
Using the formula to calculate the Pressure:
\[ \text{P} = 10 \times 1000 \times 9.81 = 98100 \, \text{Pa} \]
This demonstrates that at a depth of 10 meters in water, the pressure would be 98100 pascals (Pa).
