Elliptical vs hemispherical
The shape of the heads used can vary. The most common head shapes are: A sphere is the ideal shape for a head, because the stresses are distributed evenly through the material of the head. The radius (r) of the head equals the radius of the cylindrical part of the vessel. This is also called an elliptical head. The shape of this head is more economic… WebCalculate the liquid volume for a vertical tank and for tanks with either flat heads, dished heads, elliptical and hemispherical.
