Why is air pressure at the top of a mountain hard to breathe?
You dont breathe air pressure. You breathe air. It is harder to breathe because of the low air pressure due to the higher elavation.
What is 20 bar?
Bar is a unit of pressure. 20 bar is approximately 20 times the atmospheric pressure.
What is ten bar?
Bar is a unit used to measure pressure, one bar is the normal atmospheric pressure of the on the surface of the earth, and ten bar is when the pressure is ten times the normal atmospheric pressure on the surface of the earth.
How do scuba divers breathe underwater?
They don't breathe normally on their own.They have to use pressure regulators to breathe naturally, overcoming the extreme pressure deep underwater.A snorkel and oxygen tank help the divers breathe when they are underwater.
Why it is difficult to breathe in deep ocean?
water pressure is pushing air out of lungs... the deeper u are the more pressure, the harder to breathe
Do scuba divers breath pure oxygen?
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
If A pressure gauge reads 16.2 bar what is the pressure in kpa?
16.2 bar = 1,620 kPa
What is the Physical quantity measured in bar?
Air pressure is measured in bar.
What does 2 bar signify.?
bar is unit of pressure
What is the pressure in Bar at 10 mts sea depth.?
10 m depth is 2 bar pressure.
What is a pressure boiler?
The boilers which produces steam of pressure 80 bar or more than 80 bar are called high pressure boilers.
How many bar pressure can PN 16 valves withstand?
PN 16 valve can withstand 5 bar pressure. I have experienced that at 7 bar it cannot hold the pressure and starts to leak.
