Flow Measurement
We begin this chapter by discussing the basic principles of flow, then move on to derive the basic equations for flow velocity and volumetric flow. The chapter concludes with a discussion of the common types of flow-measur-ing devices and instruments, such as orifice plates, venturi tubes, flow nozzles, wedge flow elements, pitot tubes, annubars, turbine flowmeters, positive-displacement flowmeters, mass flowmeters, and rotameters.
