Maximum Air Pressure. This number refers to the maximum amount of air you can put in a tire before you harm it. It is not the recommended tire pressure; that number can be found in your owner's manual and on the doorjamb. Traction Rating. A traction rating can also be found on the sidewall of all modern tires.
Reid vapor pressure. Reid vapor pressure (RVP) is a common measure of the volatility of gasoline. It is defined as the absolute vapor pressure exerted by a liquid at 37.8 Â°C (100 Â°F) as determined by the test method ASTM-D-323.
The measurement commonly referred to as bottomhole pressure is a measurement of the fluid pressure in a porous reservoir. The reservoir pore-fluid pressure is a fraction of the overburden pressure that is supported by the fluid system. The other portion is supported by the rock and generates the in-situ rock stress. The overburden pressure is created by the weight of the rocks composing the lithostatic column at the point of observation.
