Hi all,

I'm almost done with my bag skirt. I have to cut out the holes for the peripheral jets. I came across a formula for the same but i could not make head or tail out of it for it wasn't clear. Please take a look at this and tell me what it means:


Does it mean A = Q / (Pb x Pc) or A = Q x Pb x Pc or any other?

Please help if you can with this formula.

The wording looked eerily familar but then I worked out why - they're a copy of the HCGBs publication 'Light Hovercraft Handbook' 1976 edition pages 14-17, which I edited, but less the diagrams which make it easier to understand! Sadly now out of print.
They've garbled the formula but heres the original page 17 which might make it easier to understand!
