How to Convert Dimension of $R$ constant of Air (J/Kg.K)?

WebQuestion: Calculate the change of internal energy of 10 kg of air modeled as the ideal gas in a closed system when the air temperature decreases from 800 K to 500 K and the specific heat ratio is 1.37. Enter the answer in kJ with the right sign. Round your answer to one digit after the decimal point.Use Table A-19 for this question. WebWhen we refer to the gas constant for air, we are referring to the gas constant for dry air. Air contains water vapor, and the amount of water vapor can fluctuate a lot, which is why we tend to ignore it. When using the mean molar mass of dry air (28.964917 g/mol), the R specific of dry air is 287.05 J/kg·K. Gas Constant - Key takeaways. WebThe atomic weight of elemental nitrogen, for example, in English units is A r,nitrogen = 14.0067 lbm/lbmol, and the molecular weight of air is ; Universal gas constant and ideal gas law.
