This is an introductory course in Engineering Science and consists of modules to expose students to the following: the science of materials used in the production of electrical engineering components; an understanding of the mechanics of fluids when driven by electrical machines; the techniques involved in the production of engineering drawings, and the function and utilization of basic mechanical workshop tools and equipment. On the electrical side, students would be taught to use the oscilloscope, meters, power supplies and signal generators, verify network theorems, design simple circuits, and perform computer simulation on these circuits.
Engineering Science and Technology is a partial-laboratory course and is assessed solely through coursework. This course has five modules: Electrical Labs and Design Project, Science of Materials, Engineering Graphics, Mechanical Workshop Technology and Mechanics of Fluids.
The Electrical module consists of four laboratory exercises, two of which are computer simulation exercises. These labs would commence in the second week of the semester. This section concludes with an individual design project, which will be used as the basis for the practical examination at the end of the semester.
The Engineering Graphics module consists of six lecture sessions, six tutorial sessions and six drawing exercises, which are used for assessment. This module would commence in the first week of the semester and would run for six weeks.
The Mechanics of Fluids module consists of lectures, tutorial sessions and one laboratory experiment. This module runs for twelve weeks of the semester and is assessed via the incourse exam and the laboratory exercise.
The Science of Materials module consists of seven lecture sessions and would commence in the seventh week of the semester. This module would be assessed using an in-course quiz.
The Mechanical Workshop Technology consists of nine workshop sessions and commences in the first week of the semester. These sessions expose students to the work processes involved in the design and construction of a flat blade screw driver and arc welding, which are assessed. Due to the hands on nature of this module, attendance will also be graded.
Labs: 25%
Written Incourse Test: 25%
Practical Incourse Test: 10%

Mechanics of Fluids Module
Notes will be made available in advance of each lecture and they should be sufficient to provide a good understanding of the material. The teaching, however, has been mainly fashioned around the textbook Mechanics of Fluids by B. Massey. Several copies exist in the Main Library and can be used for support if required; but, if needed, any sound textbook on introductory fluid mechanics will be sufficient.
There is an excellent DVD, called Multimedia Fluid Mechanics by G. M. Homsy, which gives a good visual presentation of some of the difficult concepts in the subject. Other interesting internet sources will be mentioned at the delivery of specific topics.
