2Learning Outcomes (CLO)Upon the completion of this module, the student will be able to:
CLO1: Analyze heat conduction using Fouriers Law for steady and unsteady state conditions.(C4,PLO2)
CLO2: Analyze heat transfer with the concepts of natural and forced convection. (C4,PLO2)
CLO3: Analyze heat transfer with the concepts of radiation phenomena.(C4,PLO2)
CLO4: Explain the concept of boiling and condensation phenomena. (C5,PLO2)
CLO5: Integrate design equations for heat transfer equipment (pipe heat exchangers, shell-and-tube heat exchangers, evaporator and condenser). (C5,PLO3)
SynopsisThis course will emphasize on the principles of heat transfer by conduction, convection and radiation. It will further elaborate these concepts with theories and applications to the solutions of practically relevant chemical engineering problems. Topics include steady state and transient heat conduction, force and natural convection heat transfer, radiation exchange between black and grey surfaces, heat transfer for boiling and condensation and an introduction to design heat exchange equipment - heat exchanger, condenser and evaporators.

ABSENTEEISM
Departments Policy on ABSENTEEISM.
Absenteeism is to be reported immediately to the lecturer.
Absenteeism may be acceptable on medical grounds and ifsupporting documents are presented to the lecturer.
Medical certificate (MC) or any supporting documents shall besubmitted to the lecturer within 5 calendar days inclusive of thelecture day.
Remark: from May 2014 semester onwards, do not accept MClater than the said date especially for unbarring purpose.
If students are unable to attend the test/midterm exam due to amedical condition, medical certificate must be submitted to thelecturer within 5 calendar days inclusive of the internal assessmentday. (Undergraduate Student Handbook, pg. 53)

MEDICAL CERTIFICATE ISSUE
Medical certificates from private clinics and any time off slip are not acceptable for reasons of absenteeism in internal assessment.
ONLY medical certificate issued by doctor from either a government orprivate hospital, government clinic or from UCSI Universitys clinic are accepted for further decision in replacement of assessment.
Medical Attestation Report is also to be enclosed in this form along with the original Medical Certificate.
Statements of visiting time / time off slip will not be entertained.
Submission of forged and tampered medical certificates will be referred to the Disciplinary Board for further action.
