Conservation Laws - MIT
web.mit.eduintroduced, the ideal gas law can be written as, p =(γ−1) ρE − 1 2 ρ(u2 +v2) , (81) where γis the ratio of specific heats (for air, γ≈ 1.4). You may be more familiar with the ideal gas law in the form, p =ρRT where R is the gas constant and T is the temperature. Equation 81 is equivalent to p =ρRT but Equation 81
