5. CORRECTIVE FACTORS
5.1 CORRECTION FACTORS FOR USE OF WATER-GLYCOLE MIXTURE
The correction factors for water flow rate and pressure drop must be applied to the values obtained without the use of glycol. The correction
factor for water flow rate shall be calculated to maintain the same temperature difference as would be obtained without the use of glycol. The
pressure drop correction factor is applied to the water flow rate value corrected by the water flow rate correction factor.
