Real Gas Effects
If the upstream conditions are such that the gas cannot be treated as ideal, there is no closed form equation for evaluating the choked mass flow. Instead, the gas expansion should be calculated by reference to real gas property tables, where the expansion takes place at constant entropy.

Famous quotes containing the words real, gas and/or effects:
“Pretension may sit still, but cannot act. Pretension never feigned an act of real greatness. Pretension never wrote an Iliad, nor drove back Xerxes, nor christianized the world, nor abolished slavery.”
—Ralph Waldo Emerson (1803–1882)
“... when I awake in the middle of the night, since I knew not where I was, I did not even know at first who I was; I only had in the first simplicity the feeling of existing as it must quiver in an animal.... I spent one second above the centuries of civilization, and the confused glimpse of the gas lamps, then of the shirts with turned-down collars, recomposed, little by little, the original lines of my self.”
—Marcel Proust (1871–1922)
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
