What is root mean square velocity - Definition and Meaning

Root Mean Square Velocity :

Root mean square velocity is like a wave passes around subsurface layers of various interval velocity along a specific raypath. Normally, it is greater than the average velocity by distinct percent.


Formula :

μrms = √(3RT/M)

Example :

What is the root mean square velocity of the molecules in a sample of oxygen gas at 100 °C? ==> μrms = √[3(8.3145)(100+274.15)/(32/1000)]
==> μrms = √290748
==> μrms = 539.2 m/s
