A shell may by termed as thin if its thickness to diameter ratio is less than 0.1. The factor which can be neglected in the calculation of membrane stresses is
In flash (equilibrium) distillation, a definite fraction of liquid is vaporised in such a way that the evolved vapour & residual liquids are in equilibrium with each other
Distillation under vacuum is a substitute for steam distillation
In differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation
Flash distillation, differential distillation & steam distillation are all continuous distillation processes
