Course Code: MPE 372
Course Title: THERMODYNAMICS III
Units: 3
PreRequisite: Thermodynamics, Calculus, Numerical Methods
Lecturer: E.B.K. Mutai, Dip.,(Soil & Water Engineering), (Egerton College), B.Sc. Agric. Engin. (Egerton University), M.Sc. Agric. Eng., (University of Nairobi), PhD (Environmental & Biosystems Eng. ) (University of Nairobi), on going
Purpose of the Course
The goal of this course is for students to learn to apply the fundamentals of transport phenomena to solve problems relevant to Engineering practice: Energy and mass transfer. In each case we will work through examples that help to explore both the intuitive concepts and the formal mathematical framework necessary to make predictions. Transport phenomena, along with Thermodynamics and heat transfer; Conduction, convection, heat exchangers and Radiation. define the fundamental skill set necessary for solving problems that arise in the Engineering profession.
Expected Learning Outcomes of the Course
At the completion of this course, the students will be able to:
 Set up microscopic and macroscopic energy and mass balances (conservation principles)
 Know the flux laws for heat and mass transport
 Apply the conservation principles and flux laws to model transport process central to engineering
 Use physical and mathematical similarities between the processes of heat and mass transfer to solve problems by analogy.
 Have a physical understanding of conduction, convection and radiation and heat exchangers
 Develop a sound methodology enabling the formulation and solution of a broad variety of related engineering problems.
