WebFor cooling analysis the properties of air are required from low ambient, e.g. minus 40 C, up to maximum damper temperatures of 130 C. Air can be treated for most purposes as an ideal gas. The following equations are all of good engineering accuracy over the relevant range. The relative molecular mass (molecular weight) of dry air is M A ¼ 28:965 WebAN plane wall is manufactured of solid iron with thermal conductivity 70 W/m o CARBON. Thickness of the wall is 50 mm plus front length and thickness is 1 m by 1 m. Which temperature is 150 o C on one side of aforementioned surface and 80 o C on the other. The conductive heat transfer thrown the wall can be calculated
