## What is pressure on a swimmer 10 m below the surface of Lake?

Pressure below 10 m of Surface of lake is. Let Pa be atmospheric pressure. => P = Pa+ dgh ( Here d is density if water ) => 1.05 × 10^5 + 1000 × 9.8 × 10. =>> 1.99 × 10^5 pa ➡ 2 atm is the pressure.

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

Hence pressure = 3.0 atmosphere = 3 atm.

## How do you calculate the total pressure at the bottom of a lake?

Let us calculate the pressure exerted on the bottom by the weight of the fluid. That pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container): P=mgA P = m g A .

## What is the absolute pressure 15 m below the surface of a fresh water reservoir?

Hence the required pressure at the given depth is 150 kPa.

## What is gage pressure?

Gage pressure is the most often used method of measuring pneumatic pressure. It is the relative pressure of the compressed air within a system. Gage pressure can be either positive or negative, depending upon whether its level is above or below the atmospheric pressure reference.

## Which of the following statements is true the pressure at 10 m below the surface of the ocean is about 2.00 105 Pa?

The pressure at 10 m below the surface of the ocean is about 2.00×105 Pa . Now consider the pressure 20 m below the surface of the ocean. Which of the following statements is true? The pressure is equal to that at a depth of 10 m plus the weight per 1 m2 cross sectional area of a column of seawater 10 m high.

## What is the pressure on a swimmer to Metre below the surface of water?

Hence the pressure on the swimmer is 2 atm.

## What is absolute pressure measured in?

Absolute pressure is measured relative to a full vacuum. In contrast, pressure that is measured against atmospheric pressure (also known as barometric pressure) is called gauge pressure. A full vacuum has an absolute pressure reading of 0 PSIA and average barometric pressure at sea level is ~14.7 PSIA.

## How do I calculate pressure?

Pressure on surfaces

1. To calculate pressure, you need to know two things:
2. Pressure is calculated using this equation:
3. pressure = force ÷ area.

## What is pressure short answer?

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.

3. Here,
4. P is the pressure in Nm−2.
5. The force is measured in N, and.
6. A is measured in m2.

## What is the pressure at a depth of 15m below the free surface of water in a reservoir?

Fluid Properties

Find the pressure at a depth of 15 m below the free surface of water in a reservoir. i.e., p = 147.15 kN/m2 = 147.15 kPa (Ans.)

## What is the pressure at a depth of 30 m below sea level?

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.
