What is a film in mass transfer?
The film theory has been extensively applied to describe the mass transfer in systems in which fluid phases are present. The theory considers that the resistance to mass transfer in a given turbulent fluid phase is present in a thin layer adjacent to the interface that is called a film (Seader et al., 2011).
What is necessary for mass transfer?
In the vast majority of engineering problems, mass transfer involves at least one fluid phase (gas or liquid), although it may also be described in solid-phase materials. In many cases, the mass transfer of species takes place together with chemical reactions.
Who gave film theory of mass transfer?
Lewis-Whitman
Two film theory Developed by Lewis-Whitman (1924). Assuming that • There are two stagnant layers of film at the interface. The mass transfer across the films is by molecular diffusion. The bulks of gas and liquid are homogeneous with respect to solute.

Who qualifies for mass transfer?
Who Can Complete a MassTransfer Application? Students who are completing an associate degree in an eligible program, with at least a 2.0 GPA, and are applying for admission to a Massachusetts state university or University of Massachusetts campus may complete the MassTransfer Application.
What is a mass transfer student?
MassTransfer is a statewide agreement for students transferring within Massachusetts’ community colleges, state universities and UMass campuses.
What is mass transfer in physics?
Mass transfer is the net movement of mass from one location, usually meaning stream, phase, fraction or component, to another.
How does the first step of mass transfer work?
The first step is also known as mass transfer and is carried out by convection and diffusion (1). Both events have their own rate constants. The coefficient for mass transfer k t is the same in both directions (2). The mass transfer depends on the flow cell dimensions, the diffusion coefficient of the analyte and the flow rate of the bulk solution.
What is the kinetics of mass transfer?
Mass-transfer kinetics. The mass transfer depends on the flow cell dimensions, the diffusion coefficient of the analyte and the flow rate of the bulk solution. With full or partial mass transfer, the diffusion from the bulk solution to the interaction surface is slower than the rate of binding of the analyte to the ligand.
What are examples of mass transfer processes?
Some common examples of mass transfer processes are the evaporation of water from a pond to the atmosphere, the purification of blood in the kidneys and liver, and the distillation of alcohol.
