Refrigeration and Air Conditioning The bypass factor (B. P. F.) in case of sensible heating of air is (Where td₁ = Dry bulb temperature of air entering the heating coil, td₂ = Dry bulb temperature of air leaving the heating coil, and td₃ = Dry bulb temperature of heating coil) (td₃ - td₁)/(td₃ - td₂) (td₂ - td₃)/(td₃ - td₁) (td₃ - td₁)/(td₂ - td₃) (td₃ - td₂)/(td₃ - td₁) (td₃ - td₁)/(td₃ - td₂) (td₂ - td₃)/(td₃ - td₁) (td₃ - td₁)/(td₂ - td₃) (td₃ - td₂)/(td₃ - td₁) ANSWER DOWNLOAD EXAMIANS APP
