So I'm working on my L3 project (L3 7.5" Little John) and I was doing the calculations for the number of 1/4" holes I need in the switch band of the Av-Bay and just wanted some other "eyes" to make sure my calculations are correct.
The equation I am using is from this site: https://vernk.com/AltimeterPortSizing.htm
Dn = Dt*sqrt((Aref/Vref)*(L/N))
Where:
Dn = Diameter of holes required
Dt = Inside Diameter of tube
L = Length of tube
N = Number of holes.
Here are my values:
Aref = 0.04909"
Vref = 100 cubic inches
Dt = 7"
L = 13"
N = 5
The equation simplifies down to:
Dn = 0.02216*7*sqrt(13/5)
Where Dn = 0.2501 or 1/4" - So making the number of 1/4" holes necessary to be 5. Correct?
Thanks
