Dyke capacity calculation
WebTank shell capacity in gallons or tank diameter and height in feet • Secondary containment length, width, and height in feet • If rain can collect in secondary containment: amount of … WebMay 6, 2005 · These tall dikes often occur when steel dikes are installed around steel tanks. Real estate is lacking, so the dike capacity is obtained with a tall dike. In these cases, the dike is at least ten feet largeer in diameter than the tank. Rain water collection is often a problem, so some dikes are cover. This creates a confined space entry problem ...
