FLUIDS 1. What is a Fluid ? A fluid may be defined as follows: “A fluid is a substance which is capable of flowing.” or “A fluid is a substance which deforms continuously when subjected to external shearing force, thereby capable of flowing.” 2. Characteristics of a Fluid Basic characteristics of a fluid are: 1. It has no definite shape of its own, but conforms to the shape of the containing vessel. 2. Even a small amount of shear force exerted on a fluid will cause it to undergo a deformation which continues as long as the force is applied continuously. 3. Classification of Fluids • Fluids can be classified into : 1. Liquids, 2. Gases, and 3. Vapours. • Liquid Vs. Gas: Table 2.2 summarises the various characteristics of the liquid and gas. Table 2.2. Liquid Vs Gas • Vapour: Vapour is a gas whose temperature and pressure are such that it is very near the liquid state. (Example: Steam).
