Heat And Mass Transfer Data Book By C P Kothandaraman Pdf 12


Heat and Mass Transfer Data Book by C. P. Kothandaraman and S. Subramanyan




Heat and mass transfer are fundamental phenomena that occur in various engineering applications, such as power generation, refrigeration, air conditioning, combustion, chemical processing, and more. To design and analyze these systems, engineers need to have access to reliable and comprehensive data on the thermophysical properties of materials and the empirical correlations of heat and mass transfer coefficients. However, finding such data from various sources can be time-consuming and tedious. Therefore, a handy reference book that compiles the most relevant and useful data and formulae in the field of heat and mass transfer is highly desirable.


One such book is the Heat and Mass Transfer Data Book by C. P. Kothandaraman and S. Subramanyan . This book is a popular and widely used reference book among students, teachers, and practicing engineers who deal with heat and mass transfer problems. The book was first published in 1975 and has been revised and updated several times since then. The latest edition is the sixth edition, which was published in 2008. The book has 196 pages and is divided into seven chapters: property values, conduction, radiation, convection, heat exchanger, mass transfer, and shape factor. The book is written in SI units and follows the standard notation used in heat and mass transfer textbooks.

The main features of the book are as follows:



  • The book devotes considerable space to the property values of materials (solids, liquids, and gases) that are commonly used in heat and mass transfer situations. Property values for various materials at different temperatures are given for the use of designers. The properties include density, specific heat, thermal conductivity, thermal diffusivity, viscosity, kinematic viscosity, surface tension, Prandtl number, thermal expansion coefficient, emissivity, absorptivity, reflectivity, transmissivity, Stefan-Boltzmann constant, Planck's constant, Wien's displacement law constant, and more.



  • The book provides formulae for conduction, convection, radiation, boiling, condensation, freezing, melting, heat exchangers, and mass transfer in an easily usable tabular form with symbols and units explained alongside. The formulae are derived from theoretical analysis or empirical correlations based on experimental data. The limitations and restrictions in the use of empirical relationships are also mentioned alongside. The formulae cover various geometries (plane wall, cylinder, sphere), boundary conditions (constant temperature, constant heat flux), modes of heat transfer (steady state, transient), types of fluids (laminar flow, turbulent flow), configurations of heat exchangers (parallel flow, counter flow), types of mass transfer (diffusion, convection), and more.



  • The book also contains charts and graphs that illustrate the variation of various parameters with respect to each other or with respect to dimensionless numbers. The charts and graphs are useful for interpolation or extrapolation of data or for graphical solutions of problems. The charts and graphs include temperature distribution in solids (Fourier number vs Biot number), heat transfer coefficients for forced convection (Nusselt number vs Reynolds number), radiation exchange between surfaces (view factor vs geometry), boiling curves (heat flux vs wall superheat), condensation curves (heat transfer coefficient vs Reynolds number), heat exchanger effectiveness (NTU vs capacity ratio), mass transfer coefficients (Sherwood number vs Schmidt number), and more.



  • The book also provides a list of shape factors for various geometries that are useful for calculating the radiation exchange between surfaces. Shape factors are dimensionless numbers that represent the fraction of radiation leaving one surface that is intercepted by another surface. The shape factors are given for simple geometries (parallel plates, concentric cylinders) as well as complex geometries (triangular plates, hemispherical shells) with different orientations (perpendicular, parallel) or distances (close, far) between them.




The book is a comprehensive collection of heat and mass transfer information in SI units for students and practitioners. It is intended as an adjunct to a standard text on heat and mass transfer. The book is well-organized, concise, accurate, and easy to use. It is a valuable resource for anyone who is interested in or involved in heat and mass transfer applications.
