Fundamental Concepts of Fluid Mechanicsvolume at a given temperature and pressure whereas a fixed mass of a gas occupies any available space. A liquid offers great resistance to volumetric change (compression) and is not greatly affected by temperature changes. A gas or a vapour, on the other hand, is easily compressed and responds markedly to temperature changes.

This chapter is devoted to the study of the steady incompressible flow of fluids through closed conduits, particularly those of circular cross-sectional area.

Flow in Non-Erodible Open Channels2) are applicable to flow through open channels as they are to closed conduit pressure flows. . shows the similarity of the energy concepts in both cases. It may be observed from the figure that depth (.) changes in an open channel follow the pattern of pressure (.) changes in a pipe.
