## 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 10 Metre below the surface of a pond?

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 will be the value of pressure at 20 meter depth from sea surface?

Imperial

Depth (Gauge Pressure) | Pressure (Absolute) |
---|---|

15 m/49 ft. | 2.5 bar/ata |

20 m/66 ft. | 3.0 bar/ata |

25 m/82 ft. | 3.5 bar/ata |

32 m/105 ft. | 4.2 bar/ata |

## What is pressure at 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.

Pressure is Force per Unit Area. Pressure is the force on an object that is spread over a surface area. The equation for pressure is **the force divided by the area where the force is applied**.

## 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.

## At what level would a swimmer experience more pressure?

The **deeper you go under the sea**, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .

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

Pressure within a liquid depends only on **the density of the liquid**, the acceleration due to gravity, and the depth within the liquid.

## What is the absolute pressure 30m below the surface of the sea?

The absolute pressure 30m under the sea is the sum of this gauge pressure and the atmospheric pressure: Pabs = 303, 000 + 103, 000 = **406 kPa** . the gauge pressure is Pgauge = Patms . = 0.76 m .

## How much is the atmospheric pressure at sea level?

atmosphere (atm)

(atm) unit of measurement equal to air pressure at sea level, **about 14.7 pounds per square inch**. Also called standard atmospheric pressure.
