Mean relative speed

WebWe can find the rms speed of a nitrogen molecule by using the equation. vrms = √– v2 = √3kBT m, but we must first find the mass of a nitrogen molecule. Obtaining the molar mass of nitrogen N2 from the periodic table, we find. m = M NA = 2(14.0067) × 10−3kg/mol) 6.02 × 1023mol-1 = 4.65 × 10−26kg. http://hyperphysics.phy-astr.gsu.edu/hbase/Kinetic/menfre.html

Is this the correct equation for the mean free path?

WebThe main factors that influence thermal comfort are those that determine heat gain and loss, namely metabolic rate, clothing insulation, air temperature, mean radiant temperature, air speed and relative humidity. Psychological parameters, such as individual expectations, also affect thermal comfort. WebThis means, for example, the probability that a randomly chosen event's path length is between a and b is. ∫ a b p L ( ℓ) d ℓ. The mean and RMS free paths are then defined as.
