Rms - Root Mean Square. The root-mean-square speed u is the square root of the average speeds of the molecules in a sample of gas at a specific temperature and pressure. Root mean square velocity is like a wave which passes around subsurface layers of various interval velocity along a specific raypath.
M Molecular weight of the gas.
FREE Expert Solution When calculating for root mean square speed m rms we will use the following equation. The root mean square velocity RMS velocity is a way to find a single velocity value for the particles. C rms aˆs 3RTM. M must be expressed in kilograms so M for O 2 equals 0032 kgmol.
