This app is a tool very useful for complex calculations of the gas compressibility factor Z for natural gases used in the Gas Law: PV = nRTZ. Formulas by Hall and Yarborough (1973) correlation to estimate z-factor of natural gas. Standing and Katz’s Chart to Z-Factor vs Reduced Pressure and Reduced Temperature was plotted by app using formulas by Hall and Yarborough (1973).
