please can someone help me with the equations to use for Cp and h(convection coefficient) because i am doing a finite difference problem over time, of a gas being heated, and i need these two constants to be variable as temperature changes, which at the moment they are just constants.(adsbygoogle = window.adsbygoogle || []).push({});

I think its to do with nusselt, prandtl, reynolds (of which i also dont know how to calculate, and whether they vary with temperature), and whether the convection is forced or natural.

I am looking for dCp/dt and dh/dt

If anyone can help that would be greatly appreciated
