Here we know that Franci formula:
2/3Cd(L-.1nH)(2g)^1/2 * H^3/2.
Putting the volue in this equation;
= 2/3 *.623(L-.1nH)*(2*9.8)^1/2,
= 1.8387(L-.1nH)H^3/2,
That's equivalent as;
= 1.84(L-.1nH)H^3/2.
2/3Cd(L-.1nH)(2g)^1/2 * H^3/2.
Putting the volue in this equation;
= 2/3 *.623(L-.1nH)*(2*9.8)^1/2,
= 1.8387(L-.1nH)H^3/2,
That's equivalent as;
= 1.84(L-.1nH)H^3/2.

Here, H has the power of 3/2, which is in the rectangular notch.
