Tīmeklis287 ˙ ∙ This means that for air, you can use the value R = 287 J/kg·K. If you use this value of R, then technically the formula should be written as pV = mRT , where m represents the mass of air in kg (and we avoid having to do any calculations with moles.) Relevant concepts and definitions for gases Pressure Tīmeklis1005J/kg k AND Cv = 718 J/kg k. But Cp-Cv = R. 1005-7158 = 287. Therefore R = 287 J/kg k. BIKASH said: 8 years ago. The question is R for air. The universal gas constant value is R' = 8.314 Kj/Kg.K. Gas constant R = R'/M (molecular mass of that gas). For air molecular mass = 29 (0.78*28 + 0.21*32). ...
