Refrigeration and Air Conditioning 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) (td₁ -td₃)/( td₂ -td₃) (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) ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning The bypass factor for a cooling coil Decreases with increase in velocity of air passing through it May increase or decrease with increase in velocity of air passing through it depending upon the condition of air entering Increases with increase in velocity of air passing through it Remains unchanged with increase in velocity of air passing through it Decreases with increase in velocity of air passing through it May increase or decrease with increase in velocity of air passing through it depending upon the condition of air entering Increases with increase in velocity of air passing through it Remains unchanged with increase in velocity of air passing through it ANSWER DOWNLOAD EXAMIANS APP
