Shocks: Rankine-Hugoniot Equations Here η is (671) η = β− 2 3 µ which relates β, the bulk velocity coefficient, with µ, the shear velocity coeffi- cient. Conservation of Energy The n = 2 moment expresses conservation of energy in the fluid, and equiv- alently determines the pressure P as well. Its derivation is truly marvelous
