Aims:

• To provide an introduction to the principles of transport phenomena, treating momentum, heat and mass transfer as a single unified subject and to develop skills in applying these principles to the design and specification of process equipment.
• To develop skills in solving problems in fluid flow, heat and mass transfer.

Learning Outcomes:

Upon completion of this module students should:

• understand the mechanisms of momentum, heat and mass transfer by molecular motion and by convection;
• have a knowledge of the properties of, and the differences between, laminar and turbulent flow;
• understand the concept of pressure and the instruments for measuring pressure difference;
• understand the concept of physical similarity and to be able to design experiments for scale-up purposes;
• be able to calculate average values of properties in a system by using macroscopic balance equations;
• be able to calculate a property profile in a system by using microscopic balance equations;
• have a knowledge of momentum, heat and mass transfer coefficients, film and overall coefficients;
• understand flow measuring devices.
