Notes
This application is used for sizing orifice plates, which is used with Rate Flow Control and Pressure Flow Control Values.
Instructions
  1. Fill in the flow rate and the corresponding units.
  2. Fill in the pipe size and the differential pressure.
  3. The bore size is the orifice diameter in inches.
Asumptions
  1. Water temperature is at 60 F / 16 C
  2. Specific gravity of water is 1.0
