2 Φεβ 2011 · At ambient pressure and temperature air can be regarded as a perfect gas, its properties may be described by equations: where v denotes specific volume; u is specific internal energy; R is the gas constant for air.
This report presents data on the physical properties and flow characteristics of air. These data have been compiled from several different sources outside the Department and from charts prepared within the Department. The report was prepared as a data book to be used as an aid in calculations.
29 Μαρ 2015 · The properties of Air have been tabulated below, listed by temperature in ascending order. The properties listed are density, viscosity specific heat capacity, thermal conductivity and Prandtl number. Note: Pay attention to the units for viscosity. Example: 1.6478×10 -5 kg/m.s = 0.000016478 kg/m.s.
TABLE A–9. Temp. T, 8C. Note: For ideal gases, the properties cp, k, m, and Pr are independent of pressure. The properties r, n, and a at a pressure P (in atm) other than 1 atm are deter-mined by multiplying the values of r at the given temperature by P and by dividing n and a by P.
