Problems with flow restriction orifice plates and throttling orifice plates?

Thread Content

1. “The function of a flow control orifice plate is to restrict the fluid or reduce its pressure.” When a fluid passes through an orifice plate, a pressure drop is generated. The flow rate through the orifice plate increases as this pressure drop increases; however, when the pressure exceeds a certain value (i.e., the critical pressure drop), the flow rate no longer rises. ”According to this theory, does the constant flow rate after passing through the flow control orifice plate increase or decrease compared to the flow rate before the orifice plate? How is this constant flow rate calculated? 2. “Throttle orifice plates are mainly used in orifice flow meters. When the fluid passes through the throttle orifice plate, once the flow pattern stabilizes, the flow velocity returns to its original value, but the static pressure decreases. ”Is this sentence correct?
