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: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC A nozzle is a device that is commonly used to accelerate or decelerate flow by virtue of its varying cross-section. Nozzles are widely used in aerospace propulsion systems. In rockets, propellant that is ejected from the chamber is accelerated through a nozzle to create a reaction force that propels the system. In jet engines, a nozzle is used to transform energy from a high-pressure...

We established a method of encapsulating pluripotent stem cells (PS cells) into alginate hydrogel capsules using a co-axial nozzle. This prevents cells from aggregating excessively and limits the shear stress experienced by cells in suspension culture. The technique is applicable to the mass production of PS cells as well as research on stem cell niche.

FAQs
As fluid passes through the nozzle’s constricted section, its velocity increases and its static pressure decreases. The meter therefore relies on the pressure difference between upstream and downstream pressure taps rather than on a direct measurement of moving volume. That differential becomes the input for calculating flow rate through Bernoulli’s principle and calibration data.
Bernoulli’s principle links the pressure change produced by the nozzle to the fluid’s motion, while calibration data makes that relationship usable for flow measurement. Together, they allow the measured differential pressure to be converted into either volumetric flow rate or mass flow rate, depending on the engineering requirement and reported measurement basis.
The streamlined nozzle geometry supports a controlled constriction of the flow while offering durable construction for demanding service. Resistance to erosion is especially relevant when the meter operates in systems where wear could compromise performance. This combination makes the design useful when engineers need dependable flow monitoring under industrial operating conditions.
A basic measurement workflow compares static pressure at the upstream and downstream taps, determines the resulting pressure difference, and applies Bernoulli’s principle with calibration data. The resulting calculation provides either volumetric or mass flow rate, giving operators a quantitative basis for monitoring and controlling an industrial fluid system.
Nozzle meters are suited to systems handling liquids, gases, or steam, and to installations where durable construction and erosion resistance matter. Their documented uses include process plants, power-generation facilities, and fluid-handling systems, so selection can be tied to both fluid type and operating environment requirements.
Beyond indicating flow rate, measurements from a Nozzle Meter can help engineers verify performance, manage energy use, and support safe operation. In process and power systems, tracking the calculated flow provides a quantitative basis for checking whether fluid-handling equipment performs as expected and for supporting appropriate operational control.
