Pick out the wrong statement about distillation operation

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

In differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation

Distillation under vacuum is a substitute for steam distillation

Flash distillation, differential distillation & steam distillation are all continuous distillation processes

Pressure drop due to pipe fittings can be estimated by the equation, ΔP/p = 4f.Le/D.V2/2gc, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of Le/D (dimensionless) for 45° elbow and 180° close return bends would be respectively around
