  • Not sure if this is in your realm or not, but I’m working on a diversion tunnel for a dam and we’re installing orifice pieces of varying internal diameter to slow the flow rate of the water. The orifices are being installed in order from smallest diameter to largest which seems counterintuitive to me. I would think you would go in descending diameter size to slowly restrict the flow in steps. Could you shed any light on why this would be engineered this way?
