• Level 2 core unit in the Engineering Science major sequence
• Category B broadening unit for Bachelor of Arts, Bachelor of Commerce and Bachelor of Design students
• Level 2 elective
Content This unit is taught within the integrative framework of energy and covers thermodynamics and electrical power. It provides a thorough treatment of the thermodynamic properties of pure substances, the first and second laws of thermodynamics, with applications into power plants and chillers. It also covers the fundamentals of electric circuits and the corresponding techniques of analysis, phasors and impedance, sinusoidal steady state analysis, AC power, magnetism, and the principles of electromechanical energy conversion
Outcomes Students are able to (1) apply the ideal gas equation and explain its limitations; (2) define various thermodynamic properties and determine values using thermodynamic property tables; (3) explain what interconversion of energy means, and calculate the extraction of heat and work from closed and open systems and their corresponding efficiencies; (4) solve simple problems involving thermodynamic cycles for power and refrigeration; (5) analyse electrical circuits for voltage/current and power generation/absorption behaviour; (6) analyse simple circuits involving capacitors and inductors using phasors and impedance models; (7) explain and apply the basic principles of AC, single phase, and three-phase power; (8) explain the basic principles of electromagnetism and apply these to generators, motors and transformers; (9) communicate working clearly and concisely in oral, written and visual forms; and (10) work effectively in a team and take responsibility for team outcomes.
Assessment Typically this unit is assessed in the following ways: (1) quizzes; (2) workshop activities; (3) assignments and tests; and (4) a final examination. Further information is available in the unit outline.

To pass this unit, a student must: (a) achieve an overall mark of 50 per cent or higher for the unit; and (b) achieve the requisite standard(s) for the a final examination component of the unit, as specified in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

• The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
• All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
• Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
