Specification according to DIN 28011

r1 = da
r2 = 0,1 * da
da = Da = D
h1 3,5 * s
h2 = 0,1935 * da 0,455 * s
h3 = h1 + h2
H = h3 + s
V 0,1 * (da-2*s)³ + (da-2*s)² * h1 * 0,785
Aa 0,99 * da² + h1 * da * 3,14
Ai 0,99 * (da-2*s)² + h1 * (da-2*s) * 3,14

(r1: Dish radius | r2: Knuckle radius | da: Outer diameter | h1: Straight flange height | h2: inside Depth of Dish | h3: total internal head height | s: Wall thickness | V: Volume | Aa: outer surface | Ai: inner surface)
