Calculate Minimum Port Vent Diameter
D = Minimum Port Vent Diameter V = Maximum Air Volume F = Tuning Frequency N = Number of Ports
Calculate Maximum Air Volume
V = Maximum Air Volume F = Tuning Frequency D = Minimum Port Vent Diameter N = Number of Ports
Calculate Tuning Frequency
F = Tuning Frequency V = Maximum Air Volume D = Minimum Port Vent Diameter N = Number of Ports
