Ok. I am going to calculate an approximation to the resonant frequency of a dynajet petal valve using my 'strip valve'. The reader may find the final result, surprising, as I did.

I needed some dimensions concerning the dynaJet's petal valve geometry. They aren't on the drawing so I redrew the parts that I needed.

- The 'flat' of the retainer dictates the 'free' length of the petal.
- The red outline shows 1/2 of the petal valve.
- The rectangle, of course, is the 'strip'. I'll show you how to deal with the 'left over', later.
