Pre-requisites: ChE 240, ChE 260, Math 222
Catalog Description:
The principles of heat and mass transfer in chemical engineering systems are covered. Steady and
unsteady heat transfer is examined, with emphasis on the heat exchanger design. Mass transfer by steady
and unsteady molecular diffusion and turbulent convective mass transfer is studied.

Course Objectives:
1. To develop the students’ skills in applying differential equations for describing steady and
transient heat and mass transfer problems
2. To develop the students’ skills in applying engineering design approaches for heat and mass
transfer components and systems
3. To develop the students’ skills in modeling and dimensionless analysis for heat and mass
transfer problems in different geometries
4. To provide the students with fundamental theoretical concepts and practical analysis skills
associated with convective heat and mass transfer including external and internal flow
configurations
5. To provide the students with fundamental theoretical concepts and practical analysis skills
associated with radiation heat transfer
6. To develop students’ skills in solving practical heat transfer problems using thermal resistance
networks
7. To develop students’ skills in working with contemporary heat and mass transfer related
research literature and develop their own, application driven engineering solutions working as
a team.
