Ch. V. Subbarao, P. Srinivasa Rao, G. M. J. Raju and V. S. R. K. Prasad

Different types of storage vessels are in use in chemical industries. The reasons for the choice of the typical shape or geometry may be attributed to convenience, insulation requirements, floor space, material costs, corrosion and safety considerations. The time required to drain these vessels off their liquid contents is known as efflux time and this is of utmost importance in many emergency situations besides productivity considerations. Literature reports theoretical and experimental works for arriving at efflux time. The present review focuses on the literature available on efflux time. The scope for future work is also presented in this paper.
