Comparison of Efflux Times Between Cylindrical and Spherical Tank Through an Exit Pipe
Mathematical equations for efflux time during gravity draining of a Newtonian liquid (below its bubble point) from large open storage tanks of different geometries (Where the flow in the respective tanks is essentially laminar) through an exit pipe of same length and cross sectional area (the flow in the exit pipe line being turbulent) located at the bottom of the respective tanks are developed. The equations are ultimately simplified and written in dimensionless forms. These equations will be of use in arriving at the minimum time required for draining the contents of respective storage vessels. To drain the same volume of liquid, the efflux time equations developed are compared to find out which of the tanks considered drain faster
