Mass transfer coefficient formula. It is a parameter used in the field of mass transfer, which refers to the transport of mass from one phase to another. The ‘kL’ represents the rate of molecular diffusion through the gas-liquid interface and the ‘a’ represents the area of this interface per liquid volume [1]. Heat and mass transfer relationships are next introduced to relate the rates of mass and energy transfer to the transfer coefficients and the exposed water surface area. Mastery of these concepts allows engineers to design better systems, increase process efficiency, and innovate new separation techniques. Mass transfer coefficients can be estimated from many different theoretical equations, correlations, and analogies that are functions of material properties, intensive properties and flow regime (laminar or turbulent flow). Facilitate combining resistances into overall mass transfer coefficients, , , to be used in modeling unit operations Combine resistances to mass transfer in a process unit into an overall resistance Sep 7, 2024 ยท In Chemical Engineering, Convective Mass Transfer Coefficient is a fundamental parameter which quantifies the rate at which mass is transferred between a surface and a fluid. Mass transfer coefficient, abbreviated as K, a dimensionless number, is a porportional constant to the difference in the concentrations and the rate of mass transfer. The handbook assumes that students have taken one or two semesters of chemical engineering thermodynamics, one semester of heat and mass transfer, and one semester of computational methods for chemical engineering.
