Please use the following table and note the example given.Antifreeze Correction ExampleAntifreeze solution is Propylene Glycol 20% by weight. Determine the corrected heating and cooling performance at 30°F and 90°Frespectively as well as pressure drop at 30°F for a Affinity Series Single Speed Model 022-ECM.The corrected cooling capacity at 90°F would be: 22,400 MBtu/h x 0.969 = 21,706 MBtu/hThe corrected heating capacity at 30°F would be: 14,500 MBtu/h x 0.913 = 13,239 MBtu/hThe corrected pressure drop at 30°F and 6 gpm would be: 6.6 feet of head x 1.270 = 8.38 feet of headWARNING: Gray area represents antifreeze concentrations greater than 35% by weight and should beavoided due to the extreme performance penalty they represent.Antifreeze Type Antifreeze % by wt Heating Cooling Pressure DropEWT - °F [°C] 30 [-1.1] 90 [32.2] 30 [-1.1]Water 0 1.000 1.000 1.000Ethylene Glycol10 0.973 0.991 1.07520 0.943 0.979 1.16330 0.917 0.965 1.22540 0.890 0.955 1.32450 0.865 0.943 1.419Propylene Glycol10 0.958 0.981 1.13020 0.913 0.969 1.27030 0.854 0.950 1.43340 0.813 0.937 1.61450 0.770 0.922 1.816Ethanol10 0.927 0.991 1.24220 0.887 0.972 1.34330 0.856 0.947 1.38340 0.815 0.930 1.52350 0.779 0.911 1.639Methanol10 0.957 0.986 1.12720 0.924 0.970 1.19730 0.895 0.951 1.23540 0.863 0.936 1.32350 0.833 0.920 1.399
