Understand how elevation changes atmospheric pressure (P_atm) and affects PSIG to PSIA calculations, featuring barometric formulas and altitude lookup charts.
Learn how air compressors utilize PSIG and PSIA in pneumatic calculations, atmospheric air intake ratios, pressure drop analysis, and multi-unit conversions.
Master thermodynamic gas law calculations: learn why Boyle's Law, Charles's Law, and the Ideal Gas Law (PV=nRT) strictly require absolute pressure in PSIA.
Master vacuum pressure calculations: understand how negative PSIG, inches of mercury (inHg), and microns relate to absolute zero pressure (0 PSIA).
Master pressure conversions in HVAC/R engineering: understand how gauge pressure (PSIG) and absolute pressure (PSIA) dictate refrigerant subcooling and superheat calculations.
Explore high-pressure hydraulic systems operating up to 5,000 PSIG: discover why atmospheric pressure is negligible at high pressure but critical in pump inlet cavitation.
