Study time allocation

Contact hours: Lectures: 24 Laboratories: 2 x 3 hr
Private study hours: 70
Total study time: NaN hours

Teaching and learning methods

2 lectures a week delivered by the course lecturer at which reading and problems will be set

The use of (up to) 6 optional problem classes. These will be supervised by the course lecturer. Each will be of one hour duration and specific problems which relate to material covered in the preceding lectures will be set for solution prior to each class. The final class will be a revision class for the end-of-course examination.

2 laboratories attended by the course lecturer in which students will gain hands-on experience in conducting simple fluid dynamic experiments and in preparing a technical report.

  • Attending lectures.
  • Private study and directed reading.
  • Laboratory work and report writing.
