Mixing Tank Geometry It's All About That Base

Just as the geometry of a tank's sides can affect mixing (square vs.cylindrical),the head (which is the name for the bottom of the tank,for whatever reason) can have just as much effect..There are four basic geometries of mixing tank head design flat,dished,sloped,and cone.Liquid Storage Tanks Seismic Analysis SpringerLinkA cylindrical coordinate system is usually used to describe the tank geometry with orthogonal coordinates r,,z where the origin at the centre of the tank bottom and the z axis is vertical (Fig.1).The height of the tank to the original of the free surface of the fluid and its radius are denoted by H and R,respectively; is the mass density of the fluid,while the nondimensional Liquid Storage Tanks Seismic Analysis SpringerLinkA cylindrical coordinate system is usually used to describe the tank geometry with orthogonal coordinates r,,z where the origin at the centre of the tank bottom and the z axis is vertical (Fig.1).The height of the tank to the original of the free surface of the fluid and its radius are denoted by H and R,respectively; is the mass density of the fluid,while the nondimensional
