Chapter 1: Introduction
Definition of a fluid
1. Fluid mechanics deal with the behavior of fluids at rest (fluid statics) and in
motion (fluid dynamics).
2. Fluid: a fluid is a substance that deforms continuously under the application of
a shear (tange
Chapter 3: Fluid Statics
1. Fluid deforms continuously under the application of shear stress. Thus, fluids either at rest
or in rigid-body motion are able to sustain only normal stress.
2. Analysis of hydrostatic cases is thus simpler t
Chapter 5: Introduction to differential analysis of fluid motion
1. Integral equations are useful in analyzing gross behavior of a flow field. It does not require
a detailed knowledge of the pressure and velocity variation within the co
Chapter 7: Dimensional analysis and similitude
1. The development of fluid mechanics has depended heavily on experimental results,
because few real flows can be solved by analytical method alone.
2. Experimental work in the laboratory i
EXAMPLE2i' Pressure of Saturated Liquid in a Tank
A rigid tank contains 50 kg of saturated liquid water at 90C. Determine the
pressure in the tank and the volume of the tank.
SOLUTION A rigid tank contains saturated liquid water. The pressure and vol-
