  1. 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)

  2. A.

     (td₂ - td₃)/(td₃ - td₁)

    B.

     (td₃ - td₂)/(td₃ - td₁)

    C.

     (td₃ - td₁)/(td₂ - td₃)

    D.

    Answer : Option B

    Explanation :

    The bypass factor (B. P. F.) in case of sensible heating of air is (td₃ - td₂)/(td₃ - td₁)

    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)
