WebProperties The gas constant of air is 0.287 kPa.m3/kg.K (Table A-1). The specific heat of air at the anticipated average temperature of 450 K is Cp = 1.02 kJ/kg.°C (Table A-2). Analysis (a) There is only one inlet and one exit, and thus mm m&&12= = . Using the ideal gas relation, the specific volume and the mass flow rate of air are determined ...

WebAir contains water vapor. This is important for human comfort and for A/C system design. Consider the "AIR" as a mixture of: DRY AIR = Nitrogen, Oxygen, etc. H 2 O Vapor; Temperature Range being studied (typically): -10 to +50 o C. Treat the DRY AIR as an IDEAL GAS with constant specific heat. C P = 1.005 kJ/kg-o K (use this for h = C P T or Dh ... Webspecific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree.
