Description

This unit provides students with an entry level understanding of engineering thermodynamics, heat transfer and fluid mechanics. The thermodynamics component develops basic understanding of fundamental properties and states. The First and Second Laws of thermodynamics are covered in addition to gas power cycles (internal combustion engines and gas turbines). Heat transfer introduces the governing laws of conduction, convection and radiation as well as basic heat exchangers. Fluid mechanics includes the fundamental processes and laws governing some internal and external flows.

Prerequisite Rule

(Students must pass 1 units from MAT1137, MAT1236 OR Scaled Score in MAT3C/3D > 49.99)

Equivalent Rule

Unit was previously coded ENM2108

Learning Outcomes

On completion of this unit students should be able to:

1. Apply the underlying principles of fluid mechanics, heat transfer, and thermodynamics to the analysis of basic engineering problems.
2. Describe the fundamental governing laws of thermodynamics, some fluid flows, and heat transfer.
3. Identify the effects of various physical properties and process parameters on thermofluid systems.

Unit Content

1. Basic concepts to include: temperature, pressure, heat, work, energy conversion, processes, cycles, and systems.
2. Brayton cycle.
3. Concept of entropy and entropy change (ideal gases)
4. Drag and lift.
5. First law of thermodynamics including closed systems, steady flow systems, and specific heats.
6. Heat exchanger principles and size

Assessment

GS1 GRADING SCHEMA 1 Used for standard coursework units

Students please note: The marks and grades received by students on assessments may be subject to further moderation. All marks and grades are to be considered provisional until endorsed by the relevant Board of Examiners.

Due to the professional competency skill development associated with this Unit, student attendance/participation within listed in-class activities and/or online activities including discussion boards is compulsory. Students failing to meet participation standards as outlined in the unit plan may be awarded an I Grade (Fail - incomplete). Students who are unable to meet this requirement for medical or other reasons must seek the approval of the unit coordinator.
