A survey of the physics of fluids. The fundamental principles and the range of validity of the usual approximation methods are stressed. Topics include a study of incompressible flow, both laminar and turbulent, boundary layers, stratified flow and waves, with a brief introduction to gas dynamics, magnetohydrodynamics and plasma physics.
