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

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 is the pressure 10m below the ocean?

At a depth of 10 m, the water pressure is 2 atm, double the surface pressure.

## 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 will be the pressure at a point 10 Metre below the surface of a lake of salt water?

=>> 1.99 × 10^5 pa ➡ 2 atm is the pressure.

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

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

## 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. Hope it helps.

## What is the pressure at 11km underwater?

P = 1.111473 × 108Pa(1atm)/1.013 × 105 = 1097 atm. The pressure in atmospheres at this depth is 1097 atm.

## What is the pressure below sea level?

Each one inch column that’s one foot deep will weigh 0.445 pounds. So if you’re right at sea level, the pressure will be 14.7 psi. And for every foot you go underwater, you add another 0.445 psi. So at one foot deep, the pressure would be 14.7 psi + 0.445 psi = 15.145 psi.

## What is the water pressure at 12500 feet?

The remains of Titanic are located at a depth of 12,500 feet (3.8 kilometers) depth, which has pressure of about 380 atm.

## 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.

## What is the pressure below atmospheric pressure called?

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

## 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.
