Fluid Mechanics

Module aims

  • To provide a grounding in the fundamentals of fluid mechanics, beginning with a study of fluid statics and then considering the physics governing the motion of fluids.
  • To introduce the physical processes which govern the behaviour of fluids at rest and in motion.
  • To provide a solid foundation in fundamental fluid mechanics on which specialist fluid dynamics courses in years 2, 3 and 4 will build.
  • To provide experience and confidence in problem-solving.
  • To provide insights into the practical world of civil engineering fluid mechanics.

Learning outcomes

On successfully completing this course unit, students will be able to: 

  • Understand the physical processes which govern the behaviour of fluids at rest and in motion.
  • Confidently pose and solve problems in engineering fluid mechanics.
  • Calculate the expected flow rates in pipes and open channels.
  • Perform basic design calculations.

Module syllabus

This course unit will cover topics including:  

  • Fluid properties: density, viscosity, and pressure.
  • Surface and volume integrals.
  • Fluid statics: hydrostatic pressure distribution, hydraulic presses, and pressure measurement.
  • Fluxes through control surfaces; streamlines.
  • Turbulent flows and boundary layers.
  • Control volumes, mass and volume conservation, and general conservation laws.
  • Momentum conservation and the calculation of fluid forces on structures.
  • Energy conservation; velocity measurements.
  • Pipe systems. Flow rates, major and minor losses, pumps and turbines.
  • Free surface flows; flow rates in rivers, rapidly varied flow around control structures, sub- and supercritical flow, application to bridges, weirs, and sluices.

Teaching methods

The lecture format of this module generally consists of a one hour lecture followed by a one hour tutorial in which the students can practice with the material. Students will carry out two exercises in the Fluid Mechanics Laboratory to establish a grounded view of the relation between theory and application.

Assessments

Laboratory practicals and a written examination.
