Pick out the wrong statement about distillation operation

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

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

Diameter of rivet hole (d, mm) and the plate thickness (t, mm) are related by Unwin's formula as

D = 1.6 √t

D = 1.1 t

D = 3√t

D = 1.5 t

D = 1.6 √t

D = 1.1 t

D = 3√t

D = 1.5 t
