Entry requirements

Mechanics I and Scientific Computing

Learning outcomes

After the completion of the course, the student should be able to

• apply her/his knowledge to compute fluid pressure on immersed surfaces
• visualise the flow pattern in the Eulerian approach
• use the control volume concept compute convective acceleration, local acceleration and apply Bernoulli equation to solve pressure and velocity distribution in a flow field
• interpret momentum and moment of momentum equations and their application to determine components of forces acting on fluid jets, nozzles, vanes and pipes
• apply simplified forms of energy equation to determine power required by a pump to lift a fluid mass to a certain height or power delivered by a turbine due to height loss etc.
• use the concepts of laminar and turbulent flow, calculate velocity distribution, energy losses 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.

Content

Properties and changes of state for fluids and gases, equilibrium of fluids (hydrostatics), conservation principles in kinematics (moving coordinate systems, the control volume concept, Eulerian and Lagrangian methods), energy and continuity equations, stress-strain relations, differenatial analysis of fluid motion Euler and Bernoulli equations, similarity analysis, laminar and turbulent boundary layers, uniform and non-uniform flows in open and closed systems (flow in pipes). Demonstration: 1. Energy distribution and losses in a closed hydraulic system 2. Sub-critical and Super critical flows in open channels

Instruction

Lectures, exercises, laboratory demonstrations and reports.

Assessment

Examination is held at the end of the course. Grading on the scale 3, 4 or 5 is given provided all exercises and laboratory reports are completed and deemed approved. A student who fails the examination can be examined again either at the beginning of the autumn or the spring term.
