The Fixed Area Hydraulic Orifice uses an alternative equation that I am unfamiliar with since it differs from the textbook/classic orifice equation. Here are the questions I have:
- What is the difference between the two?
- Do the Cds from the classic formulation carry over to the Simulink variation?
- Does Simulink adjust Cd in relation to the Reynolds number?
Im working on a system level simulink model and need more of an understanding of the orifice inputs to ensure a good engineering model.
