The Chézy equation is a pioneering formula in the field of fluid mechanics, and was expanded and modified by Irish engineer Robert Manning in 1889 [1] as the Manning formula. The Chézy formula concerns the velocity of water flowing through conduits and is widely celebrated for its use in open channel flow calculations. [ 2 ]
The Chézy Formula is a semi-empirical resistance equation [1] [2] which estimates mean flow velocity in open channel conduits. [3] The relationship was conceptualized and developed in 1768 by French physicist and engineer Antoine de Chézy (1718–1798) while designing Paris's water canal system.
A MacBook Air (15-inch, M2, 2023) running macOS Ventura. On June 6, 2022, during the 2022 Worldwide Developers Conference (WWDC), Apple announced their second-generation processor, called M2, with an improved performance versus the previous M1 processor. The first computer to receive this new chip was a radically redesigned MacBook Air.
On the same date, the 13-inch M2 MacBook Air received a price cut from $1199 to $1099. [22] On March 4, 2024, Apple announced a refreshed M3 MacBook Air in both 13-inch and 15-inch sizes. This model retains the same design as the M2 MacBook Air, but adds support for two external displays when the lid is closed.
Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, the iPad Pro and iPad Air tablets, and the Vision Pro mixed reality headset.

If more than one formula is applicable in the flow regime under consideration, the choice of formula may be influenced by one or more of the following: Required accuracy; Speed of computation required; Available computational technology: calculator (minimize keystrokes) spreadsheet (single-cell formula) programming/scripting language (subroutine).
Atkinson resistance is commonly used in mine ventilation to characterise the resistance to airflow of a duct of irregular size and shape, such as a mine roadway. It has the symbol and is used in the square law for pressure drop,
