Detailed Description

The Physics class combines EquationOfState and HeatTransfer to calculate the new state of a pipeline given a new pressure, temperature and flow.

This class operates on a Pipeline instance, and returns a new Pipeline instance with updated properties (heat flow, Reynolds number etc.)
