Select the appropriate unit and enter a value and click on "Calculate". The result will be displayed.
L = Length of Vent or Port
D = Diameter of Vent
N = Number of Ports
V = Volume of Box
F = Tuning Frequency
K = End Correction Factor
\(L=\frac {2.35625×10^4×D^2×N}{V×F^2}-K×D\)
Known data: diameter of vent; number of ports; volume of box; tuning frequency; end correction factor, what is the vent length?
Input data: diameter of vent--10 cm; number of ports--10; volume of box--5 liters; tuning frequency--5 Hz; end correction factor--5, click "Calculate" to display the result.
Output: vent length: 1.8845×105cm
