There will be a 50-minute test during week 6 in tutorial rooms during tutorial time, and it will cover material from weeks 1 to 5.
Prescribed Textbook: Cengel, Turner and Cimbala, Fundamentals of Thermal-Fluid Sciences 3rd EDITION IN SI UNITS (McGraw Hill). Available at both the UBS and Vol. 1 bookshops. IMPORTANT: It will be difficult to pass this course unless you own this text ! EES Software: Engineering Equation Solver (EES) is a thermodynamics and fluids software package which can be used in solving many problems. It is especially strong in the thermodynamic and fluid property data which it has available. You can use EES for problem solving and tutorial work. A reduced copy of EES is available with the Textbook, and some help may be available from the course lecturers and tutors. ____________________________________________________________MECHENG 211 Thermofluids 20/07/2009 1
Philosophy: The emphasis in this paper is on •
basic principles and their application to simple, ideal and real systems; and
•
integration of thermodynamics, fluids and heat transfer into useful systems.
What you need to know: To pass this paper you need to learn to solve basic problems in thermodynamics, heat transfer and fluid dynamics. This means that you must be able to: •
understand all the definitions and the conservation laws (mass, momentum and energy)
•
find properties of substances, and determine their phase
•
recognise when you can make approximations
•
decide correctly which equations apply to particular processes
•
describe your solutions clearly and unambiguously.
Note:
This paper introduces many new concepts which you must understand, so the material does not lend itself to last-minute cramming for exams. Therefore, you are expected to: 1. Attend the tutorials; and 2. Devote at least 6 hours to this course each week, in addition to the 4 contact hours. You may spend such time towards reading material and examples from the text and then attempting problems from tutorial sheets and the text.
