Sphere and spheroids

Storage Spheres and Spheroids - The total exposed surface within 7.5 m of grade, or up to the elevation of the maximum horizontal diameter, whichever is greater, is used. 

The wetted area of the tank or storage vessel shall be calculated as follows For spheres and spheroids, the wetted area is equal to 55 percent of the total surface area or the surface area to a height of 30 feet (9.14 meters), whichever is greater. For horizontal tanks, the wetted area is equal to 75 percent of the total surface area For vertical tanks, the wetted area is equal to the total surface area of the shell within a maximum height of 30 feet (9,14 meters) above grade. 

In the three matrix elements shown in the bottom half of Fig. 13.14, there appear to be less pronounced differences between spheres and nonspherical particles. Perry et al. pointed out that near the forward direction S 34/511 is rather sensitive to the parameters of the size distribution, while measurements for both kinds of particles—rounded and cubic—agree quite well with calculations. Similar agreement between calculations for spheres and spheroids was noted by Asano and Sato (1980). This combination of sensitivity to size distribution and insensitivity to shape might be put to good use in particle sizing. 

This is the title of Chapter 3 in Ref. [9], Advances in Quantum Chemistry, Vol. 57, dedicated to confined quantum systems. The conoidal boundaries involve spheres, circular cones, dihedral angles, confocal paraboloids, con-focal prolate spheroids, and confocal hyperboloids as natural boundaries of confinement for the hydrogen atom. In fact, such boundaries are associated with the respective coordinates in which the Schrodinger equation is separable and the boundary conditions for confinement are easily implemented. While spheres and spheroids model the confinement in finite volumes, the other surfaces correspond to the confinement in semi-infite spaces.

The validity of Eq. (197) is confirmed by the results plotted in Fig. 34. As can be seen, the linear dependence given by Eq. (197) reflects well the exact numerical results derived from the RSA simulation for spheres and spheroids. The proportionality constant was found to be equal to 2.3 (for < )o = 200, which is a typical value for the colloid particle interactions). This indicates...
