It is required to design a storage tank to store propane in a chemical plant. The topography of the plant is such that the best location for the storage vessel is 200 meters away from the control room. The other equipment in the plant will be farther away from the storage vessel for safety reasons. The control room has been designed to withstand the explosive overpressure of 2.5 psig. Design the storage vessel Operating pressure of the vessel is 200 psig. You may assume it is a spherical vessel
