Summary of Content

The main objective of the module is to provide the student with fundamental concepts of momentum transfer which emphasize fluid statics, fluid dynamics, fluid metering, fluid transportation, pressure drop in packed and fluidized beds To provide the student with basic knowledge on heat transfer and its applications in Process Operations field.

Syllabus

Fluid Mechanics: Fluid; classification of fluids; Introduction to fluid statics and dynamics, manometers and pressure gauges; fluid flow; types of fluid flow; Reynolds number. Boundary layer concept. Basic equations of fluid flow: Bernoulli's equation and its application. Fluid flow regimes: velocity profile; shear stress distribution; Hagen Poiseullie's equation; concept of average velocity; concept of hydraulic radius; flow of fluids through pipes and tubes. Concept of fluid friction - friction factor &Reynolds number relationship. Flow through packed and fluidized beds. Flow past immersed bodies and flow through packed bed, significance of form friction Heat Transfer : Conduction - Heat transfer by conduction, general heat conduction equation, thermal diffusivity & equivalent thermal conductivity, linear one - dimensional steady state conduction through slabs, cylinders, spheres & composite walls Convection - Concept of & examples convective heat transfer; concept of hydrodynamic and thermal boundary layers. Heat transfer coefficients (Individual and Overall), Overall heat transfer coefficient, LMTD correction factors for multiple pass heat exchangers predictive equations for heat transfer coefficients Thermal Radiation: Concept and examples of radiative heat transfer. Stefan-Boltzmann law and Wien's displacement law Heat Transfer Equipment's: Types of Heat Exchangers;. Double pipe and shell and tube heat exchangers. Evaporator and its types

Learning Outcomes

On completion of this module the student should be able to1. Describe, apply and analyze the concepts fluid statics. (AM1)2. Describe, apply and analyze the concepts of fluid flow through pipes, packed and fluidized beds. (AM1, AM2, AM8)3. Explain hydrodynamic boundary layer on a flat plate and circular pipe. (AM1)4. Discuss fluid transportation and metering. (AM2, AM8)5. Illustrate and apply the principles of conduction, convection and radiation modes of heat transfer. (AM1, AM8)6. Discuss different heat transfer equipments and evaluate the heat transfer characteristics in double pipe heat exchangers. (AM2, AM8)

Teaching / Learning Strategy

Synthesis of class room lectures with power point projections, guest lectures, seminars, tutorials and plant visits. Team work, practical application of engineering fundamentals. Tutorials will be used to reinforce the module material discussed during lecture sessions. It also serves as a platform of technical discussions to clarify any queries that arise from directed studies .
