WebIn practice most expansion and compression processes are somewhere in between, or said to be polytropic. The polytropic process can be expressed as pVn = constant (3a) or p1V1n = p2V2n (3b) where n = polytropic index or exponent (ranging 1 to 1.4) Sponsored Links Related Topics Fluid Mechanics - The study of fluids - liquids and gases. WebDec 31, 2024 · One of the most dangerous properties of liquid nitrogen is its ability to boil into large volumes of gas. The liquid-to-gas expansion ratio is 1:694 at 20ºC/68ºF. This means 1 L of liquid nitrogen can expand to 694 L of gas. [3] If enough liquid boils in a confined space, the air can be displaced, resulting in an oxygen deficiency.
