## What is pressure on a swimmer 10m?

PS=**2atm**. Hence the pressure on the swimmer is 2 atm. ∴ The pressure on a swimmer 10 m below the surface lake is 2 atm, thus, option (D) is correct. Note: We can see from the answer that the pressure at a depth of 10m is much more than the pressure at the surface of the lake.

## What is the absolute pressure at a depth of 10m in a lake?

Hence, the Pressure at the depth of 10 m is **198 kPa**.

## When the pressure is measured above absolute zero it is called?

The atmospheric pressure at sea level (above absolute zero) is called ‘**Standard atmospheric pressure**‘. … (Vacuum pressure is defined as the pressure below the atmospheric pressure).

## 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 pressure on a swimmer 20m below the surface?

Hence pressure = **3.0 atmosphere = 3 atm**.

## Can a pressure be negative?

Absolute pressure is measured relative to absolute zero on the pressure scale, which is a perfect vacuum. (**Absolute pressure can never be negative**.)

## 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 .

## How do you convert pressure to depth?

We begin by solving the equation P = hρg for **depth h:** **h=Pρg h = P ρ g** . Then we take P to be 1.00 atm and ρ to be the density of the water that creates the pressure.

## Why does water pressure increase with depth?

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. … The greater pressure at the bottom would give a greater ‘force per unit area’ on the wall.

## 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.

## 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.
