Flow Measurement & Control interview Practice QA
Precise measurement and control of fluid flow through pipes is extremely important in almost all process industries. Flow is the study of fluids in motiona fluid is any substance that can flow, and thus the term applies both to liquids and to gases. There are several devices and instruments available for measuring fluid flow. Each is designed to measure accurately and efficiently in a variety of applications, although some flowmeter designs perform better with certain applications. Different process industries measure flow for different reasons, and one flowmeter may be used for more than one application even within one industry. This practice test will introduce you to the most common reasons for measuring flow, why and how each of the four basic types of flowmeters work. You will also learn about important aspects to consider when selecting a flowmeter for a particular application, as well as the benefits and limitations of each flowmeter design currently in common use. This practice test Covers Interview questions frequently asked on following topics with Answers and necessary explanations: Common reasons for measuring flowFlow EquationsGeneral terms used in flow measurementThe importance of the three key variables used in flow equationsHow following fluid properties affects flow measurement: Density Viscosity Fluid type Flow profileThe importance of temperature and pressure in steam flow measurementsThe three types of flow profile and how they occur Laminar, Turbulent & TransitionTypes of flow profile disturbances and how each may be created and eliminated Symmetrical profile disturbanceAsymmetrical profile disturbance & SwirlFlowmeter SelectionDP FlowmetersVelocity FlowmetersMass FlowmetersPositive Displacement Flowmeters
