Course Aim (s):

To introduce the fundamentals of fluid mechanics used in the analysis of problems involving static fluids and simple fluid flows.

To allow students to appreciate the implications of the principles of thermodynamics and apply them to relatively simple situations.

Intended Learning Outcomes:

➢    carry out fluid pressure measurements and calculate the forces and moments exerted on plane and curved surfaces by fluid at rest.

➢    explain velocity field and flow pattern in fluid flow around bluff body

➢    calculate pressure variation in one-dimensional steady frictionless fluid flows and forces exerted by simple fluid flows.

➢    relate the macroscopic thermodynamic behaviour of systems to the microscopic nature of matter.

➢    apply the Second Law, to determine the reversibility in thermodynamic processes, and to estimate the performance of heat engines.
