torisphericalDomeType

The meridian of the dome is a spherical dish of radius R₁ at the apex, joined tangentially to a knuckle of radius R₂ at the cylinder. Because the two arcs are tangent, their centres and the point at which they meet lie on one line, and the dome height h and the polar angle of that point follow from the two radii and the cylinder radius R alone.

h = R1 - sqrt((R1 - R2)^2 - c^2), with c = R - R2 and sin(alpha) = c/(R1 - R2)

R₁ is larger than the cylinder radius, and R₂ lies between zero and the cylinder radius. The flatter the dish, the larger R₁ and the smaller the dome height.

The excerpt is the pressure vessel of the example tank: a dish radius of 2.4 m and a knuckle radius of 0.4 m give a dome 0.61 m high at a cylinder radius of 1.3 m.
