Examine the statement that at a given temperature, a lighter molecule will have smaller viscosity coefficient but larger heat conductivity coefficient. 7.8.5 Compute electron and ion collision frequency with magnetic induction 10,000 Gauss. [Ans: 1.759e11; 2.4168e6 s -1 ] Show that the ratio of the Mach number, Ma = U/v sonic , and the Reynolds number, Re = nM UL/µ=, is approximately equal to ?/L. Herein U = flow speed and L = a characteristic flow length.
