PN 16 valve can withstand 5 bar pressure. I have experienced that at 7 bar it cannot hold the pressure and starts to leak.

1 bar = 14.5 psi. If you mean gauge pressure, ie pressure above atmospheric, 6 bar would be 87 psig
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
30-40 bar peak pressure
1 bar is 14.5 PSI so it would be 11.6 PSI
275
It means the makers claim it is waterproof to 10 bar pressure. One bar is normal atmospheric pressure, about 14.7 psi, so it should withstand 10 times normal pressure. A depth of approximately 330 feet.
14.7psi.
You can't really convert that. Kilogram is a unit of mass, bar is a unit of pressure; so they really measure completely different things.
90 meters. Every 10 meters, the pressure increases by approximately 1 bar, to this, you have to add the atmospheric pressure, which is also approximate 1 bar.
- The meter is a unit of length, the bar a unit of pressure.- If you think to the object bar the length is very variable
Ton is a weight and bar is a pressure. There is no conversion between the two.
Bar is a unit of pressure. 20 bar is approximately 20 times the atmospheric pressure.
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.
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.
Inlet & exhaust valves operate in different pressure conditions. Inlet valve in NA engines (Normally aspirated engines) have to work against pressure difference of say vacuum caused by piston going down & atmospheric 1 bar pressure, ie at pressure difference of 1 bar while exhaust valve has to work against pressure of multiple times of 1 bar. So exhaust at high pressure has a tendency of getting exhaled faster. During designing of valve size, amount of force required to operate the valves during operation is also considered so higher the area of exhaust valve higher is the force required to operate it. Thirdly Valve overlap timing requirement & the dynamics of the flow of air and physical sizes of valve opening affects each other or dependent of each other
