Drag TechnologySeptember 20, 2022
In the United States, two 640 MW 2×1 combined cycle sister plants have received permits to upgrade their facilities. Both plants will switch from water-cooled condensers to air-cooled condensers, eliminating the use of ocean water for cooling. However, the conversion to air-cooled condensers was not without risk. Strict long-range noise requirements related to neighboring residential areas were a significant obstacle. The plant owners needed a low-noise solution for the turbine bypass valves located upstream of their new air-cooled condensers to complete their modernization plan.
IMI CCI’s sales and application engineering team worked closely with the end user, EPC, and OEM to define comprehensive technical requirements for the air-cooled condenser system and recommended system solutions that meet the plant’s stringent noise requirements. The IMI CCI solution provided multi-stage DRAG® technology to eliminate valve skirt noise and an under-plug configuration to mitigate the potential for low-frequency seat bore recombination and valve expansion noise.
In addition, stringent far-field noise requirements required the use of multi-stage DRAG® technology for critical and typically noisy startup ventilation applications.

In computer graphical user interfaces, drag is a pointing device gesture in which the user selects a virtual object by “grabbing” it and dragging it to another location or to another virtual object. In general, it can be used to invoke many kinds of actions or create different types of associations between two abstract objects.
Drag and drop support is not a feature found in all software, although it is sometimes a quick and easy technique to learn. However, it is not always clear to users that an item can be dragged and what the drag command is, which can reduce usability.
Move the pointer to the object Press and hold the button on the mouse or other pointing device to “grab” the object “Drag” the object to the desired location by moving the pointer to that location “Drop” the object by releasing the button
Dragging requires more physical effort than moving the same pointing device without holding any buttons. Because of this, the user cannot move as quickly and precisely when dragging (see Fitts’ Law). However, drag operations have the advantage of thoughtfully combining two operands (the object to be dragged and the location of the drag) into a single action. Prolonged dragging (as in graphic design) can strain the mouse hand.
There is a design problem when the same button selects and drags items. Inaccurate motion can cause an attempt to select an object to be registered as drag motion.
The user would have to stop the drag, make both the source and target visible, and start again. In classic Mac OS, the top menu bar served as a universal destination for drag-and-drop cancellation. This issue was resolved in Mac OS X with the introduction of Exposé.
Dragging, then called click-and-drag, was used on the original Macintosh to manipulate files (such as copying them between drives or folders.
In 7.5, drag and drop was extended to common clipboard operations, such as copying or moving text content in a document. Content can also be dragged into the file system to create a “snip file” that can be saved and reused.
For most of its history, Mac OS used a one-button mouse, with the button covering much of the top surface of the mouse. This can alleviate ergonomic issues with holding the button while dragging.
