## 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?

Example – Air pressure at Elevation 10000 m

Altitude Above Sea Level | Absolute Atmospheric Pressure | |
---|---|---|

feet | metre | psia |

25000 | 7620 | 5.45 |

30000 aprox. Mount Everest, Nepal – Tibet | 9144 | 4.36 |

35000 | 10668 | 3.46 |
