Question

purpose of water inlet and outlet during distillation

Answer 1

Answer:

The cold water inlet is positioned below the outlet, ensuring that if air bubbles are in the water they will rise due to buoyancy and be swept out of the outlet by the water pressure.

Answer 2

Water inlet is used to reduce the heat transfer efficacy and water outlet is used to remove the air bubbles if any inside the distillation tube during distillation.

DISTILLATION:

• Distillation is an age old purification technique.
• In this process the liquid is evaporated to vapour which is again cooled back to the liquid.
• The water inlet and outlet in the distillation tube plays imporatant roles.
• The water outlet is placed to let the air bubbles if any is caught in the distillation tube.
• If air bubbles is present,it rises due to buoyant force and will be drawn out of the tube through water outlet due to water pressure.
• Water inlet is used to reduce the heat transfer efficacy.
