I think characteristic_length is a better name than reference_length since it won't get confused with the one for moments and is also more common definition used in defining Reynolds number globally I believe.

  • project_length_unit was renamed to characteristic_length
  • fixed unittests
  • fixed previously ommited operating_condition_from_mach_reynolds() calls

For reference, here is a Wikipedia page where it is also called characteristic length.
