This chapter presents an overview of the physical
properties of fluids, a review of basic concepts, and
covers the fundamentals required to understand
the theory of measuring flow, which is presented in
Chapter 3.
A fluid is a substance that continues to deform when
subjected to a shear stress. Fluids can be liquids,
vapors, or gases. For most fluids, some of the fluid
properties can be calculated by knowing other
There are five key fluid properties that must be known
to properly size and use a DP flowmeter: density
or specific weight, static pressure, temperature,
isentropic exponent and viscosity. These properties
factor into DP Flow calculations.
