Concept explainers

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

25.A tank contains 80 ft³ of air at a pressure of 350 psi. If the air is cooled until its pressure and temperature decrease to 200 psi and 70•F respectively, what is the decrease in internal energy?
A balloon is surrounded by a tank of liquid at negative pressure and is con- nected to the atmosphere by a tube of length L and cross-sectional area A (Fig. 7.25). The pressure inside the balloon p oscillates above and below atmospheric pressure causing small changes in the balloon volume V. The elasticity of the balloon is characterized by its compliance C, defined by Ap = AV/C (a) Derive a second-order differential equation for AV(t), assuming that (i) the pressure differential along the tube accelerates the air in the tube and is not used to overcome entrance, exit, or tube losses; and (ii) the air density p is constant. From the equation, show that the natural frequency of the system is JA/pLC.
