Why is it hard to control flow in an open system? I am getting undesired flow from the reservoir to the tank however how much I specify the demand at different nodes. I don't want to use a flow control valve since it adds excessive/abnormal head to my model not a similar case in the real life scenario since the position of the flow control valve is right at the intake structure /weir. My worry is that I Fear it might have less to near NO effects unlike it has been exaggerated.
see the attached .how can I cure this?
positioning the FCV at the end of the pipeline cured my problem guys. Thanks for your support family
