The set up consists of glass column, packing material, air rotameter and piping. Metered quantity of airflow is passed through the packed bed vertically upwards. The flow rate can be independently varied to simulate different conditions using rotameter. Naphthalene balls of known weight and diameter are used to form the packed bed for the calculation of mass transfer co-efficient of vaporization in air.
