## What is the pressure on a swimmer 20m below the surface of water?

Hence pressure = 3.0 atmosphere = 3 atm.

## What is the pressure on a swimmer 20 m below the surface of a lake take G 10 m S²?

Hence the pressure on the swimmer is 2 atm. \$therefore \$ The pressure on a swimmer 10 m below the surface lake is 2 atm, thus, option (D) is correct.

## What is the pressure at 10 m below the ocean surface?

At a depth of 10 m, the water pressure is 2 atm, double the surface pressure.

## What is the pressure at the surface of water?

If you are at sea level, each square inch of your surface is subjected to a force of 14.6 pounds. The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.

## Which of the following is NOT unit of pressure?

Out of the four options, we know that pascal, torr and atm are units of pressure. Therefore, dynes is not a unit of pressure. Dyne is a unit of force.

## What is the pressure 30m below the surface of a lake?

For every additional 10 meters deeper you dive, the pressure on your body increases by 1 bar. As you can see from the table below, our bodies are subject to 3 bars or atmospheres of pressure at a depth of 20 meters and 4 bar/atm at 30m.

## What does the pressure of a liquid depend on?

The pressure in a liquid is different at different depths. Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.

## How much pressure can a human take underwater?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

## How much pressure is 7 miles underwater?

While atmospheric pressure in the average home or office is 14.7 pounds per square inch (PSI), it is more than 16,000 PSI at the bottom of the Mariana Trench.

## What is the pressure at 35000 feet?
