Hugoniot condition
WebMass Conservation • Mass flowing into the shock must exit from the other side! • Normal mass flux is ρu x • The MHD mass conservation or continuity Webthe condition p 2 >> p 1, this is called a strong shock. Consider a strong shock for a monatomic gas (= 5 3). From the jump conditions the limit of a strong shock is that ˆ 2 ˆ 1 = + 1 1 = u 1 u 2: (14) For = 5 3, we get that this ratio is 4. Note that all this work has been done with respect to the shocks reference frame. That is,

It is given in general terms but it is the proof I was looking for. So the Rankine-Hugoniot condition stays the same in the case (2),(3) as in the case (1),(3). But what happens to the speed? In the conservation law case (1),(3) shock speed is constant.
