Most modern cars are built with organic acid technology (OAT) antifreeze (e.g., DEX-COOL [25]), or with a hybrid organic acid technology (HOAT) formulation (e.g., Zerex G-05), [26] both of which are claimed to have an extended service life of five years or 240,000 km (150,000 mi). DEX-COOL specifically has caused controversy.
The path or series of states through which a system passes from an initial equilibrium state to a final equilibrium state [1] and can be viewed graphically on a pressure-volume (P-V), pressure-temperature (P-T), and temperature-entropy (T-s) diagrams. [2] There are an infinite number of possible paths from an initial point to an end point in a ...
The underlying property data for the Mollier diagram is identical to a psychrometric chart. At first inspection, there may appear little resemblance between the charts, but if the user rotates a chart ninety degrees and looks at it in a mirror, the resemblance is apparent. The Mollier diagram coordinates are enthalpy h and humidity ratio x.
Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...

On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia. On the right-hand vertical axis, locate and mark the point containing the temperature 60°F. Connect the points with a straight line. Note where the line crosses the methane axis. Read this K-value off the chart (approximately 21.3).

Once two of the three reduced properties are found, the compressibility chart can be used. In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found.
