Inside the distillation column, the

Occurrence of 'case hardening' during drying of a high moisture solid cake __________ the drying rate.

Which of the following is not a continuous drier ?
-
Humidification involves mass transfer between a pure liquid phase and a fixed gas, which is
-
__________ is the temperature at which a gas-vapor mixture becomes saturated, when cooled at constant total pressure out of contact with a liquid.
-
Rate of leaching increases with increasing
-
An azeotropic mixture is a __________ mixture.
-
Pick out the wrong statement.
A.
In the McCabe-Thiele diagram for binary distillation, vertical feed line represents saturated liquid feed and horizontal feed line represents saturated vapour feed.

B.
In small columns, local efficiency is larger than Murphree efficiency; in large columns local efficiency is smaller than Murphree efficiency.

C.
For Laminar flow over a plate of length L, the local mass transfer co-efficient at a distance L from the leading edge is 1.5 x 10-2m/s. Then the average mass transfer co-efficient for the plate is 2 x 10-2m/s.

D.
The concentration and hydrodynamic boundary layers over a flat plate are of equal thickness, if Schmidt number is equal to unity.
