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)

The bypass factor (B. P. F.) in case of sensible heating of air is (Where t_d₁ = Dry bulb temperature of air entering the heating coil, t_d₂ = Dry bulb temperature of air leaving the heating coil, and t_d₃ = Dry bulb temperature of heating coil)

a) (td₂ – td₃)/(td₃ – td₁)

b) (td₃ – td₂)/(td₃ – td₁)

c) (td₃ – td₁)/(td₂ – td₃)

d) (td₃ – td₁)/(td₃ – td₂)
