Fluid Flow Measurement, 3rd Edition

Basic Flow Measurement Laws

The chapter goes through the laws which should be recognized and obeyed before flow measurement is attempted. Certain physical laws explain what happens in the “real” world. Some of these laws explain what happens when fluid flows in a pipeline, and these in turn explain what happens to a flowing stream as it goes through a meter. The laws discussed in this chapter include the law of “conservation of mass”, also called the “Law of Continuity,” the law of “conservation of energy”, the Fluid Friction Law and the fundamental flow equation. The Reynolds number is explained, as are the gas laws and ways to correct for the effects of temperature and pressure.
