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 iterative procedure calculates the vapor pressure of a liquid fraction for the. conditions specified by the RVP test, namely, original sample at 35oF, pressure test started at 60oF, equilibrium. vapor/liquid volume of 4 (i.e., V/L = n = 4), and final equilibrium pressure measured at 100oF. The algorithm uses.
