No, 200 psi of air is not the same as 200 psi of water. This is because water is denser than air, so the pressure exerted by water at 200 psi would be greater than that of air at the same pressure.
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
You cannot directly convert water psi to air psi as they are different units of pressure with different properties. Water pressure is typically measured in psi (pounds per square inch) to denote the pressure exerted by a column of water, while air pressure is also measured in psi but refers to the pressure of the air in a confined space. It is not a straightforward conversion, so it is important to measure and calculate each pressure separately based on the specific conditions.
factory air pressure norm is 80 psi
14.7 Psi
In an FMVSS121 compliant air brake system, cut out pressure is between 115 - 130 psi, with a cut-in pressure of no more than 25 psi below cut-out pressure. The 90 psi figure is what the brake chambers are regulated at, not the entire system.
Air pressure decreases by about 1 psi for every 10°F increase in temperature. Conversely, air pressure increases by about 1 psi for every 10°F decrease in temperature.
Cut out pressure is between 115 and 130 psi... cut in pressure is no more than 25 psi below the cut out pressure.
If it is fresh water, and the surface is at sea level, then the pressure at the surface is 14.69 psi. As you submerge, then the pressure from the weight of the water above you is added to the air pressure above the water. For each foot that you descend, the water pressure will increase by 0.4331 psi, so at 328 feet deep, the water pressure is 142.0568 psi. Add the 14.69 psi air pressure to get 156.7468 psi.
psi is air pressure per square inch normally for your tyres
The atmospheric pressure at the level of the Dead Sea is approximately 15.47 PSI.
7.5 PSI.
