Source: Laboratory of Dr. Zhongqi He - United States Department of Agriculture Acids and bases are substances capable of donating protons (H+) and hydroxide ions (OH-), respectively. They are two extremes that describe chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. A substance that is neither acidic nor basic is neutral. The values of proton concentration ([H+]) for most solutions are inconveniently small and difficult to compare so that a more practical...

Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Turbulent flows exhibit very high frequency fluctuations that require instruments with high time-resolution for their appropriate characterization. Hot-wire anemometers have a short enough time-response to fulfill this requirement. The purpose of this experiment is to demonstrate the use of hot-wire anemometry to characterize a turbulent jet. In this...

Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI The purpose of this experiment is to demonstrate the calibration of a flow passage as a flowmeter using a control volume (CV) formulation [1, 2]. The CV analysis focuses on the macroscopic effect of flow on engineering systems, rather than the detailed description that could be achieved with a detailed differential analysis. These two techniques should be...

FAQs
Different flow-meter designs rely on different measurable consequences of transport. A device may interpret a pressure change, fluid velocity, heat transfer, or an electromagnetic property as evidence of how much fluid passes through the sensing region. This choice links the instrument’s signal to the type of flow being studied, allowing investigators to select measurements suited to liquid, gas, or specialized bioengineering systems.
Pressure-, velocity-, heat-transfer-, and electromagnetic-based measurements do not observe flow in the same way. Each uses a different property that changes as fluid moves through a sensor, then relates that change to transport through the system. Recognizing the underlying property helps researchers understand what the instrument is sensing and interpret readings appropriately in bioengineering experiments.
Flow rate may be expressed as volume per unit time or mass per unit time, so the reporting format matters when results are compared or used for control. Volume-based values describe how much space the transported fluid occupies over time, whereas mass-based values describe the amount of material transported. Choosing the appropriate representation keeps measurements aligned with the experimental question.
To use a flow meter measurement, researchers place the sensor in the fluid transport pathway, monitor the property selected by the instrument, and interpret the resulting signal as a flow-rate value. They can then use that value to monitor transport or control delivery. In a bioengineering setup, this workflow connects an observed sensor response with an operating condition that can be evaluated across experiments.
Within bioreactors, measurements can be used to monitor and regulate perfusion, the movement of fluid through the engineered system. In microfluidic devices, they help verify that fluid delivery is occurring as intended. These uses make flow data relevant both to ongoing process control and to checking whether a device produces the transport conditions required for an experiment.
Blood-mimicking and physiological flows provide another application because their transport behavior can be characterized quantitatively. Flow-meter data also supports medical-device design and engineered-tissue development by documenting the conditions under which fluid moves through a system. When measurements are reliable, they contribute to reproducible experiments and help researchers evaluate whether intended transport conditions are maintained.
