P. 336 Finally we can relate the pressure p to the density n and temperature T by 3.37 19 In modelling plasmas, Kinetic theory (3.3) is close to exact but mathematically complicated, while the two fluid (electrons and ions 3.4) treatment is simpler mathematically and usually accurate. However, for some applications it is sufficient, and again simpler mathematically to consider a plasma as being a single fluid.In the single fluid approximation the dynamics of the plasma are the same as for classical fluid dynamics but with the additional complication that the fluid is electrically conducting and so capable of interacting with magnetic fields. The word magnetohydrodynamic is often abbreviated to MHD can you show me step by step how to get 3.38 The momentum equation in the magnetohydrodynamic approximation is obtained by adding the momentum equations for the electrons and ions given above (3.36). We have 3.38 upon using equation 3.31 with p-0 and equation 3.32. The density has been set to N nm in 3.38 and the single fluid velocity
