4 Νοε 2012 · In the imperial system the most common units for the individual gas constant are ft lb/slug o R . In the SI system the most common units are J/kg K . Unit conversion: 1 J/kg K = 5.97994 ft lb/slug °R, and 1 ft lb/slug °R = 0.167226 J/kg K.
11 Φεβ 2021 · The gas constant (R) is a proportionality constant used in the ideal gas law and Nernst equation. It’s also called the ideal gas constant, universal gas constant, or molar gas constant. Basically, the gas constant is the same as the Boltzmann constant (k), except the gas constant includes Avogadro’s number (N A): R = NA k.
In SI units the value of the gas constant, R, is: R =8.314510 Pa m3 K-1 mol-1 = 8314.510 Pa L K-1 mol-1 = 0.08314510 bar L K-1 mol-1. This table gives the appropriate value of R for use in the ideal gas equation, PV = nRT, when the variables are expressed in other units.
The gas constant occurs in the ideal gas law: = = where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. R specific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.
The gas constant can also be expressed in terms of energy units (e.g., R 8.3143 J/mol 3K); note that J N 3m (N/m2)m Pa m . In this case, the conversion from one unit system to another is given by R 8.3143 E unit J K T unit gg m unit. . . . . . . . . . . . . . . . .
