Talk:Rankine–Hugoniot equation

From Wikipedia, the free encyclopedia

[edit] Greater explanation needed

I find this article very difficult to understand. It seems to have much assumed knowledge, and many of the symbols are undefined. It would benefit greatly from practical examples and applications, and full definitions of symbols. (Not to mention reputable references) Sholto Maud 02:38, 31 May 2006 (UTC)

[edit] difficutl article

i do agree that this article is based on previous knowledge i would need some change do be more understandable

[edit] Problem on the energy flux equation

The last equation (energy flux) contains a unit mismatch, that is to say, different units are added.

The first component (e- Internal energy) is [Cv x T] (Cv- specific heat in constant volume, T- temperature) the unit is [J/mol]

The two other added parts are [P/roh] and [1/2 x u^2] both of which have the same unit [(m/sec)^2] yet different from the first (e).

I don't see how you can add the three [ e+P/roh+(1/2 x u^2) ].

... unless the equation is per unit mass...

Is it?

Yes. Lowercase e and ρ indicate that the quantities are specific (meaning, that they are per unit mass). Titoxd^{(?!? - cool stuff)} 20:56, 1 March 2008 (UTC)
