 Pipe Flow  a PDH Online Course for Engineers 
  For turbulent flow the pipe roughness and the Reynolds number are used to evaluate the friction factor from the Colebrook equation. 
  Benefits to be derived from this course include these: Awareness of the fluid properties of viscosity and compressibility, knowledge of the differences in governing equations for compressible, incompressible, isothermal, and adiabatic flow, use of the Reynolds number to determine laminar or turbulent flow, calculation of energy losses, and different methods of solving the governing equations. 
  For both compressible and incompressible fluids, and for isothermal and adiabatic gases, the governing equations of continuity, momentum, and energy were presented.
