Covers industrial-process control valves and gives flow capacity test procedures for evaluating variables used in the equations given in IEC 534-2. The variables covered are: flow coefficient, liquid pressure recovery factor, combined liquid pressure recovery factor and piping geometry factor, piping geometry factor and pressure differential ratio factors. Comments on determination of liquid critical pressure ratio factor and Reynolds number are given.
