Measurement of Flow and Fluid Properties
In previous chapters we have looked briefly at several flow-measuring devices such as the venturi meter and the pitot tube. In our study of laminar viscous flows we also studied several flow cases that were suited to the measurement of fluid properties. In this chapter we elaborate on some of the details of these devices to better understand their use, and also introduce other types of measuring instruments. The devices are divided into the following categories: measurement of velocity, measurement of mass rate or volume rate, measurement of pressure, measuremen t of viscosity.
