Hemispherical Head Design to ASME VIII-1
Calculate the requred wall thickness or maximum allowable working pressure of an ASME VIII-1 Hemispherical Head under internal pressure.
UG-16 (minimum thickness calculation), UG-79 (forming strain), UG-28 (external pressure) is not included in this calcualtion
To use this calculation t<0.356L and P<0.665SE
