I am not entirely sure how some of these steps work.(adsbygoogle = window.adsbygoogle || []).push({});

What I have so far (pardon any latex mistakes, I am new to it)

change in pressure over volumetric strain = K the bulk modulusCode (Text):K=\frac{\Delta P}{\Lambda Vol /Vol}

Code (Text):\rho Vol'= d \rho / dtI am unsure about this step del P to dP/dt i understand but not the strain term.Code (Text):(\frac{d P}{d t}/\frac{d \rho}{d t}*)\rho=K

Code (Text):\frac{d P}{d t}= \frac{K}{p} * \frac{\rho}{dt} = K Vol'

V is velocityCode (Text):Vol'=div(V)

becauseCode (Text):\frac{d P}{d t} = K div (V)Code (Text):\frac{d P}{d t} =div(M*grad(P))These last two steps I don't understand apparently \frac{d P}{d t} =div(M*grad(P)) is some kind of identity. And because I don't understand this step I don't understand what value M should have.Code (Text):div(M*grad(P))= K div (V)

Any light on these would be awesome thanks. Sorry its kinda messy im very new to latex
