How can I calculate Reynold’s number for a complex model?

  I have attached the model pic and the model itself (.step)
  
  Disclaimer: I am very new to CFD and my fluid dynamics is a little rusty (have started on fixing this)
  
  If it was a simple model, I would have calculated the Reynold's number on paper and then would have known what to put in Ansys fluent. But for such a complex geometry, I don't know how to proceed.
  
  Help?

  I wasn't sure how you wanted to see the design, let me know if this is sufficient or not

  Please insert your screenshots here. You can base your Re number on characteristic length and velocity scales. This has nothing to do with CFD knowledge.
