Lecture 4: Pressure and Wind
www.ess.uci.eduThe Ideal Gas Law An equation of state describes the relationship among pressure, temperature, and density of any material. All gases are found to follow approximately the same equation of state, which is referred to as the “ideal gas law (equation)”. Atmospheric gases, whether considered individually or as a
Notes on the Euler Equations
bender.astro.sunysb.eduApr 16, 2013 · The equations are closed with the addition of an equation of state: p =ρe(γ −1) (5) where γ is the ratio of specific heats for the gas/fluid (for an ideal, monatomic gas, γ =5/3). In this form, the equations are said to be in conservative form. They can be written as: Ut +[F(U)] x =0 (6) with U = ρ ρu ρE F(U)= ρu ρuu+p ρuE+up (7)
