Compressed Air Velocity Calculator, Formula, Compressed Air Velocity Calculation

Compressed Air Velocity Calculator:

Enter the values of Air flow rate Q_(ft³_/m) & Diameter of the pipe d_(inches)   to determine the value of Compressed Air Velocity Vca_(ft/s).

Compressed Air Velocity Formula:

The Compressed Air Velocity Vca_(ft/s) in feet per second is equal to the Air flow rate Q_(ft³_/m) in feet cube per minute is Divided by the value of 60 and multiply the 3.141 value and again multiply the Diameter of the pipe d_(inches) in inches divided by the value of 24 for squared.

The Equation of Compressed Air Velocity can be writtern as,

Vca_(ft/s) = Q_(ft³_/m) / ( 60 * pi * ( d_(inches) /24 )² )

Here,

Vca_(ft/s) = Compressed Air Velocity in feet per second

Q_(ft³_/m) = Air flow rate in feet cube per minute

d_(inches) = Diameter of the pipe in inches

Example Problems for Compressed Air Velocity:

1)Calculate the Compressed Air Velocity and given for Air flow rate = 250ft³/s , Diameter of the pipe = 4inches.

Answer

Vca = Q / ( 60 * pi * ( d / 24 )² )

Vca = 250 / ( 60 * 3.141 * ( 4 / 24 )² )

Vca = 47.75ft/s.

2)Calculate the Diameter of the pipe and given for Air flow rate = 250ft³/s , Compressed Air Velocity = 47.75ft/s.

Answer

Vca = Q / ( 60 * pi * ( d / 24 )² )

47.75 = 250 / ( 60 * 3.141 * ( d / 24 )² )

d = 4inches.
