Calculating Tank Wetted Area - Chemical Processing

A spheroidal head must be a hemispheroid; only a hemispheroid is valid – no “segment” of an spheroid will work as it will in the case of a spherical head where the head may be a spherical segment. For a spherical head, |a| £ R, where R is the radius of the cylindrical tank body. Where concave conical, hemispheroidal,
