What is the pressure on 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 is the pressure at the 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.
What is the absolute pressure 30m below the surface of the sea?
to three significant figures. 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 .
What does the pressure of a liquid depend on?
The pressure in a liquid is different at different depths. 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.
How much pressure can a human take underwater?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
