This script discusses the different properties of fluids. In a general context, fluids are classified as either a liquid or gases, although in other textbooks, it also incorporates plasma as part of its scope. The coverage of this script is limited to the detail discussion of the fluid properties such as the density, viscosity, compressibility and elasticity, vapor pressure, surface tension and capillary rise or depression. Specific problems are presented with detailed solutions to guide the reader on the step by step procedure of solving in an engineering point of view.
The study of fluid mechanics is utilized in the field of engineering most specifically on engineering structures that incorporates the conveyance of fluids in the system. Pipelines and machines like turbines and engines also use the principles of fluid mechanics. Thus, it is cognizant to learn the basics of the properties of fluids in order to have a better grasp of the principles of fluids in application to engineering works. The units that were used in the illustrations are all in metric system.

It is defined as the negative ratio of differential pressure change to the relative change in volume (K = - dp / (dV / V0)).
What is the difference between dynamic and kinematic viscosity?
Dynamic viscosity expresses resistance to shearing flows, while kinematic viscosity is defined as the ratio of dynamic viscosity to mass density.
How does the book explain capillary rise?
It is explained as a phenomenon occurring when the adhesive forces between a liquid and a solid are greater than the cohesive forces within the liquid.
