2024年5月16日 · It's the same with vacuum chamber gauges. Instead of going from 14.7-0, they go from 0 to around -30 PSI. I highly doubt this. They probably go from 0 to around -30 inches of mercury (often labeled 'inHg' or '"Hg'). 1 inch of mercury is about 0.49 PSI, so -30" is about -15 PSI, which matches up very nicely to what you would expect a good vacuum ...

Clearly a much stronger tire but an illustration of the principle that exposure to vacuum does not automatically equate to tires exploding. While not complete vacuum, airliners will fly at altitudes of up to 50k feet where the air pressure is 1.7 psi. Their tires are inflated to 200-250 psi and are not maintained in pressurized compartments

The 14.7 psi atmospheric pressure is an absolute measurement. It's 14.7 psi more than absolute 0 psi. The psi measurement in your tire is a relative measurement. If it reads 32 psi, that means its 32 psi more than the atmospheric pressure. It's absolute psi …

2024年5月23日 · To convert kilopascal (kPa) to pounds per square inch (psi), you can use the conversion factor of 1 kPa = 0.145038 psi. Simply multiply the pressure in kilopascal by 0.145038 to get the equivalent ...

2023年8月10日 · 1 psig is equivalent to 51.71 mm (2 in) of Mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal ...

2015年4月16日 · The air we all live in every day on earth is at 14.7 psi absolute or 0 psi gauge. No surprise why they would make it the same in space. In space, a vacuum, the pressure is basically 0 psi absolute so the pressure inside the ISS would be 14.7 psi absolute and also 14.7 psi gauge at the same time.

2024年5月20日 · Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch). But water pressure ...

2024年4月8日 · Some measure absolute pressure, in which case the deflated tire will register 14.7 PSI. You can get gauge-pressure, which measure the difference between the pressure in the tire and the outside air, in which case a deflated tire will read 0 PSI. Or, you can get "sealed-gauge", which is just like the absolute pressure gauge, minus 14.7 PSI.

2024年5月21日 · The total pressure at sea level is approximately 14.7 psi (standard atmospheric pressure). With a boost of 8 psi from the turbocharger, the total pressure being fed into the engine would be 22.7 ...
