WebApr 10, 2024 · For example, the viscous work done by a cross-country skier is calculated as the product of distance travelled and the resisting force (the product of gravitational acceleration, the mass of the skier plus skis, and the coefficient of sliding friction for a given wax, temperature, and snow condition). viscous work WebJun 29, 2024 · The convective term can often be neglected, as can pressure-work effects. Viscous heating can also be of interest for Stokes flows in bearings and other lubrication applications, for example. Turbulent Flow. The Reynolds number measures the importance of the inertial effects compared to the viscous effects.
