Hi everybody, I have a problem with this equation:(adsbygoogle = window.adsbygoogle || []).push({});

it represents the motion of a gas in a duct with friction (Fanno flow). I need to plot this function in a T-s plot, do you have any ideas? the Mach number changes along the curve...

R=constant

S_{2}-S_{1}=R*(M^{2}-1)*log(T_{2}/T_{1})$
