Knowing the required flow coefficient for a specified flowrate, this calculator determines the size of orifice to suit. The reciprocal calculation is also possible whereby, knowing the orifice diameter, the coresponding flow coefficent can be determined.

• Orifice Diameter to Flow Coefficient - Calculate the flow coefficient, Kv, cv, or Av, from a given orifice diameter.

• Flow Coefficient to Orifice Diameter - Calculate any orifice diameter from a given flow coefficient, Kv, cv, or Av.
