is it correct modeling mathematical model for Compressed air engine,(adsbygoogle = window.adsbygoogle || []).push({});

As here air Flowing through Pipe in Kg/s and its not a continuous flow and flow through vent in to the cylinder and pushes Piston and and Piston moves down.

As I created model like this

(P1*V1)^Y = (P2*V2)^Y

So,

P2 = [(P1*V1)^Y] / [ (V1+dV)^Y ]

here i m in Confusion can i use this equation for my case because this does not includes density term

or Please guide more what equation i can use here.
