Entry requirements

120 credits with at least 90 credits in Earth Sciences and 15 credits mathematics, or 90 credits in Physics.

Learning outcomes

On completion of the course, the student should be able to:

• compute fluid pressure on immersed surfaces
• visualise the flow pattern in the Eulerian approach
• use the control volume concept to derive simplified one-dimensional forms of the conservation equations of mass, momentum, and energy.
• compute convective and local acceleration and apply the Bernoulli equation to solve for the pressure and velocity distribution in a flow field.
• apply the concept of the momentum and moment of momentum equations to determine components of forces acting on fluid jets, nozzles, vanes and pipes
• apply of the energy equation to determine viscous losses, power required by a pump to lift a fluid mass to a certain height, or power delivered by a turbine due to a drop in elevation.
• use the concepts of laminar and turbulent flow, calculate velocity distribution, and discharge through circular pipes with joints and in natural and lined open channels in a steady flow field
• solve problems concerning varied flow in open channels using the concept of specific energy.

Instruction

Lectures, exercises, and laboratories.

Assessment

Grading is based on a written exam (4 credits) and written lab reports (1 credit).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
