Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, `sigma`= yield strength and E = modulus of elasticity)

Souders Brown equation given by,`U = K_V sqrt((pL-pv)/(p_v))`
, is used for the calculation of the __________ in a continuous distillation column.
