As promised, I prepared some flow numbers, (based on a reference text for design flow guidelines), and I must say that I am surprised as to what the results were.

The reference chart has sharp edged orifice diameters and pressures, with SCFM amounts for a diameter at different pressures. I had a reference text at one time that had a formula that you could plug in an area, pressure differential, temp of air, and depth of the orifice, and it would give you the flow rate +- a touch. Not absolute, but would give you an idea if the design was in the ball park for the application. After the move I found some stuff, and lost some stuff.

Any way, I took a .125 Inch Dia. (This is America so inches rules the day LOL), and found the area of the diameter, .0122716 sqin.

I then multiplied that area X 4 holes to get a total area of .0490864 sqin.

I then reversed the process and found the single diameter that has the area of all four .125 dia holes (.0490864), and the single hole size is .2499966 inch diameter.

At 100 psi the chart said that a .125 sharp edged orifice will flow 26 SCFM, X 4 holes = 104 SCFM (actual about 75%)

At 100 psi the chart said that a .250 sharp edged orifice will flow 104 SCFM (actual about 75%)

I must say that I am surprised to see that they flow the same. There is not a consideration for length, like a tube, but the wall thickness of the PC is not much, (it may be a ratio of a percentage of the diameter sort of thing). I really like Hercules approach of tapering his holes which thins the tubular portion of the hole as well as funnels in air and creates a rapid pressure drop when the gasses are expelled from the PC.

Perhaps some one more knowledgeable can comment on the flow math. I thought there would be more of a loss with the smaller holes.
