Question

Calculate a pressure on a diver 100 m below the surface of an ocean

Answer 1

P =pgh so P=1000×9.81×100 Pa

Answer 2

Given:

• The depth of the diver below the surface of the ocean = 100m

To Find:

• The pressure on the diver.

Solution:

We already have the formula to find the pressure which is given by,

P =  $P_0$ + ρgh → {equation 1}

Where "$P_0$" is the atmospheric pressure is constant ( 1.05× Pa), "ρ" is the density of water which is constant( 1000 Kg/), "g" is the gravitational force(9.8 m/), and "h" is the depth.

On substituting the values we have in equation 1 we get,

⇒ P = 1.05×$10^5$+(1000×9.8×100)

Remove the brackets in the above formula and perform multiplication and addition operations. We get,

⇒ P = 9.45× $10^5$ Pa

∴ The pressure on the diver = 9.45× $10^5$Pa.
