WebIt is common to distribute a mixture of propane (C 3 H 8) and butane (C 4 H 10) for combustion purposes. Propane is more suited to colder environments since it evaporates at -44 o F (-42 o C) at atmospheric pressure. Butane evaporates at 33 o F (0.6 o C) at atmospheric pressure. WebHow to Read a Pressure-Enthalpy Diagram In chemical engineering, it is often necessary to know how properties like pressure, enthalpy, volume, and entropy relate to each other at a certain temperature.
