Equivalent Diameter of Circular Duct for Rectangular Duct when Quantity of Air is Same

Go Equivalent Diameter of Duct = 1.256*((Longer Side^3*Shorter Side^3)/(Longer Side+Shorter Side))^0.2

Equivalent Diameter of Circular Duct for Rectangular Duct when Velocity of Air is Same

Go Equivalent Diameter of Duct = (2*Longer Side*Shorter Side)/(Longer Side+Shorter Side)

Reynolds Number in Duct

Go Reynolds Number = (Diameter of Circular Duct*Mean Velocity of Air)/Kinematic Viscosity

Quantity of Air given Velocity

Go Quantity of Air = Velocity of Air*Cross-Sectional Area of Duct

Velocity Pressure in Ducts

Go Velocity Pressure in Ducts = 0.6*Mean Velocity of Air^2

Reynolds Number given Friction Factor for Laminar Flow

Go Reynolds Number = 64/Friction Factor in Duct

Reynolds Number given Friction Factor for Laminar Flow Formula

Reynolds Number = 64/Friction Factor in Duct
Re = 64/f
