Using Snap Cutters. 1  1. Use chalk to mark cut lines on the pipe. 2  2. Wrap the chain of the snap cutter around the pipe as evenly as possible. 3  3. Apply pressure onto the handles of the cutter so the wheels cut into the pipe.  4. Repeat these steps at all other chalk lines.
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 100 Â°F (37.8 Â°C) as determined by the test method ASTM-D-323. The test method applies to volatile crude oil and volatile nonviscous petroleum liquids, except liquefied petroleum gases.
vaâ²por pres`sure. n. the pressure exerted by the molecules of a vapor. vapor pressure. 1. The pressure exerted by water vapor in the atmosphere. 2. The pressure exerted by a vapor on the solid or liquid phase with which it is in equilibrium. At pressures lower than the vapor pressure, atoms or molecules of the liquid or solid being vaporized can escape from the surface of the liquid or solid.
