Learning Outcomes
Knowledge and Understanding:
On successful completion of the module, students should be able to demonstrate knowledge and
understanding of:
Thermodynamics:
• the equation of heat transfer as applied to problems of plane and circular geometries
• the first law as applied to engineering systems
• the steady flow energy equation as applied to a control volume
• the determination of the performance of steam power plant using steam tables
Mechanics of Fluids:
• basic dimensional analysis to reduce a physical problem to non-dimensional form.
• the principle of dynamic similarity to scale model data to full-scale
• U-tube and inclined-tube manometers to measure applied pressure differences.
• the horizontal and vertical components of the hydrostatic forces exerted on submerged surfaces, and the
lines of action of those force components.
• Bernoulli's equation as applied to internal and external flow problems
• cavitation and the conditions under which it will occur in a liquid flow
• the hydrodynamic forces which arise due to changes in the velocity and direction of a fluid stream..
