- Q4. Why diameter required is large in vaccum distillation?
- Ans.
Large diameter is required in vacuum distillation to reduce pressure drop and prevent clogging.
Reduced pressure in vacuum distillation causes lower boiling points and higher vapor velocities.
Large diameter helps to reduce pressure drop and prevent clogging of the equipment.
Smaller diameter can cause higher pressure drop and slower vapor velocities, leading to reduced efficiency.
Large diameter also allows for better hea...
