| 11. | Where is the molar mass, is the pressure, is the universal gas constant, and is the absolute temperature.
|
| 12. | Where " f c " is the percolation threshold and " R " is the universal gas constant.
|
| 13. | :You may want to have a look at gas constant and Boltzmann constant for a more detailed treatment of the topic.
|
| 14. | It is common, especially in engineering applications, to represent the specific gas constant by the symbol " R ".
|
| 15. | In such cases, the universal gas constant is usually given a different symbol such as " " to distinguish it.
|
| 16. | The specific gas constant for dry air is 287.058 J / ( kg�K ) in United States customary and Imperial units.
|
| 17. | Finally, in units of mol / ( m 2 �s ) and the gas constant R, one obtains the more familiar form:
|
| 18. | Here R is the gas constant and T the absolute temperature, and U ij is the energy between molecular surface i and j.
|
| 19. | Where is the molar flux, is the gas constant, is the temperature, } } is the effective Knudsen diffusivity of the porous media.
|
| 20. | Where : \ sigma _ 0 and E factors depended on electrolyte materials, T electrolyte temperature, and R ideal gas constant.
