We present protocols to be used in the measurement of spray droplet size from agricultural nozzles used in both aerial and ground based agrochemical applications. These methods presented were developed to provide consistent and repeatable droplet size data both inter- and intra-laboratory, when using laser diffraction systems.

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.

In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...
FAQs
Consistent nozzle-to-workpiece distance and orientation are central to uniform delivery. The drive mechanism holds the nozzle at a defined position while controlling travel speed, so the process medium reaches successive areas under comparable motion conditions. This coordination helps produce repeatable spray patterns and material distribution, making the system useful when engineers compare operating conditions rather than uncontrolled movement.
Manual movement can change the nozzle’s location, travel speed, distance, or orientation from one pass to another. A Nozzle Traverse System constrains these factors through a defined path and controlled drive motion. Reducing operator-dependent variation improves repeatability, allowing differences in spray patterns or material distribution to be interpreted as process effects instead of inconsistent handling.
The main controllable variables are nozzle position, travel speed, distance from the workpiece, and nozzle orientation. Changes in any of these can alter where the process medium is delivered and how evenly it is distributed. Treating them as defined parameters allows engineers to evaluate their effects systematically and identify operating conditions that produce more consistent results.
A typical setup establishes the nozzle’s path relative to the workpiece, then defines its position, travel speed, distance, and orientation. The system can subsequently move through the selected path while maintaining those conditions. Engineers may repeat the run with deliberate parameter changes, creating comparable trials for assessing spray patterns, material distribution, or other process outcomes.
Applications include coating, surface treatment, manufacturing, and experimental testing. In production-oriented work, controlled motion supports more consistent delivery across a target surface. In laboratory or development work, the same control helps engineers compare process settings and examine how movement conditions affect the resulting spray pattern or material distribution.
Controlled traversal makes parameter changes more systematic because nozzle motion is less dependent on individual operator technique. Engineers can examine different positions, travel speeds, distances, or orientations while preserving a defined movement pattern. This improves measurement reliability and helps identify optimized operating conditions for the process medium, whether the goal is coating, treatment, manufacturing, or testing.
