should run on all pushes
…substance (currently only nitrous) from a polynomial. Also began an orifice class (still non-functional) that will make use of the enthalpy function.
…ter for properties. Note that Chemical.Cp appears to be producing bogus results for nitrous, and needs to be fixed. Currently the expression is replaced by the value at 255K for debug.
… the bug causing the supercritical polynomial to be used by the thermo solver for Cp if a temperature under 65K was not computed previously in that runtime since the last calculation of a supercritical Cp or the beginning of the runtime.
Refactored `Manifold` code to be compatible with new `Chemical`-inherited `Fluid`
current issues:
-Solver finds solutions, but they appear to increase mass flow rate as you approach pressure drop=0, and continue to climb with inverse drops.
-Entropy is calculated assuming that liquid and gaseous entropies are equal at a value close to the critical point, which may be causing integration errors
-specific volume can be calculated in many ways, to produce many different results, as far as i can see the current solution is accurate.
Help is welcomed
