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

Contents

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 on the swimmer 20m below the surface of water?

Hence pressure = 3.0 atmosphere = 3 atm.

## 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.

## 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.

## What is the pressure at 15 m?

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

## 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 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.

## What is gauge pressure class 11?

Pressure difference between the system and the atmosphere. From relation P=Pa+ ρgh where P= pressure at any point, Pa = atmospheric pressure. We can say that Pressure at any point is always greater than the atmospheric pressure by the amount ρgh. P-Pa=ρgh where.

## How do you calculate gauge pressure?

Gage pressure is indicated by pg, and is related to absolute pressure as follows: pg = p – pa, where pa is the local atmospheric pressure. Example: A car tire gauge measures a tire pressure of 32.0 psi. The local atmospheric pressure is 14.2 psi.

## How do you calculate actual pressure?

The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: Pabs = Pg + Patm where Pabs is absolute pressure, Pg is gauge pressure, and Patm is atmospheric pressure.

## What is the pressure below atmospheric pressure called?

If the measured pressure is below atmospheric pressure it is called negative or vacuum gauge pressure.

## Where is the low pressure area?

In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere. The formation process of a low-pressure area is known as cyclogenesis.

## How do you calculate absolute pressure underwater?

To find the absolute pressure, we must add in the 14.7 psi of atmospheric pressure. 22.25 + 14.7 = 36.95 Thus the pressure for a depth of 50 feet in sea water is 36.95 pounds per square inch absolute. It is common to refer to this as “PSIA”, pounds per square inch absolute.
