the friction coefficient is determined by the auto-correlation function of the inter-molecular forces via Eq. (189). In this sense, Eq. (189) may be viewed as a generalization of the Stokes formula. Alternatively, in the usual theory
Wind speed profiles (i.e., variation with height) for a flat terrain characterized by a roughness length of 0.01 m and for a friction velocity of (τ/ρ)1/2=0.5 m s−1. The three different curves correspond to an atmosphere that is neutral (has an adiabatic lapse rate), stable, ...
For a class of generalized kinetic equations on the half line with nonreflective half range boundary conditions and modeling various equations from radiative transfer, neutron transport, and gas kinetics, we express the internal field solution in generalizations of Chandrasekhar's H-functions. Contrary ...
I gave you the work formula for friction, so take the total energy just before the rough patch and plug it into the conservation of energy equation. Then take the formula for work that I gave you (which should have come up in class, I'm sure), and plug that in. Then set the whole...
