Is this the right format of the energy equation (equation 2.10)?
http://www-solar.mcs.st-and.ac.uk/~alan/sun_course/Chapter2/node3.html#energy
[tex]
\frac{\rho^\gamma}{\gamma-1}\frac{D}{Dt}\left(\frac{p}{\rho^\gamma}\right)=-L
[/tex]
I know it in a different format:
[tex]
\frac{dp}{dt}+\gamma p\nabla\cdot\mathbf{v}=-L
[/tex]
Where is the difference coming from?
