I need to design restricting orifice plates and flow orifice plates. Medium in both cases is water at 175 F.

There are many calculators on line for orifice plate design. Are these calculators equally applicable to both restricting orifice plate and a flow orifice plate design?
Are there any differences in there design and configuration requirements and do different standards for design apply such as square edge - rounded edge - plate thickness,discharge side bevels?

For restricting orifice plate designs the Client provides me pipe ID and orifice plate hole size, flow, upstream pressure and temperature and is requesting permanent pressure loss at max flow. The restricting orifices have no downstream pipe with discharge below the water surface of a lake.

For flow orifice plate designs the Client provides me pipe ID and orifice plate hole size, flow, upstream pressure and temperature and is requesting permanent pressure loss at max flow and delta P at full scale flow.


Thanks
