The bypass factor, in case of sensible cooling of air, is given by (where td₁ = Dry bulb temperature of air entering the cooling coil, td₂ = Dry bulb temperature of air leaving the cooling coil, and td₃ = Dry bulb temperature of the cooling coil)

(td₂ -td₃)/( td₁ -td₃)

(td₃ -td₂)/( td₁ -td₃)

(td₃ -td₁)/( td₂ -td₃)

(td₁ -td₃)/( td₂ -td₃)

(td₂ -td₃)/( td₁ -td₃)

(td₃ -td₂)/( td₁ -td₃)

(td₃ -td₁)/( td₂ -td₃)

(td₁ -td₃)/( td₂ -td₃)
