WebRoot mean square speed (v rms) is defined as the square root of the mean of the square of speeds of all molecules. It is denoted by v rms = √v 2. Equation (9.8) can be re-written as, From the equation (9.18) we infer the following (i) rms speed is directly proportional to square root of the temperature and inversely proportional to square ... WebSurface roughness is an important parameter that affects the tribological behavior of surfaces, e.g., asperity interlocking or deformation can increase friction. Figure 18.8 plots the root-mean-square (RMS) roughness of these carbon films as measured by an atomic force microscope (AFM) versus sulfur content.
