Manning formula. The Manning formula or Manning's equation is an empirical formula estimating the average velocity of a liquid in an open channel flow (flowing in a conduit that does not completely enclose the liquid). However, this equation is also used for calculation of flow variables in case of flow in partially full conduits, as they also ...
Manning is from an old Norse word — manningi — meaning a brave or valiant man; and one of the first forms of the name was Mannin; another cartography was Mannygn. [1] One historian gives a Saxon origin for the family, which he calls "ancient and noble". According to him, Manning was the name of a town in Saxony, and from it the surname sprang.
Hydraulic roughness is the measure of the amount of frictional resistance water experiences when passing over land and channel features. [1] One roughness coefficient is Manning's n-value. [2] Manning's n is used extensively around the world to predict the degree of roughness in channels. Flow velocity is strongly dependent on the resistance to ...
Robert Manning (22 October 1816 – 9 December 1897) was an Irish hydraulic engineer best known for creation of the Manning formula. Manning was born in Normandy, France, the son of a soldier who had fought the previous year at the Battle of Waterloo. In 1826 he moved to Waterford, Ireland and in time worked as an accountant.
A steel man argument (or steelmanning) is the opposite of a straw man argument. Steelmanning is the practice of applying the rhetorical principle of charity through addressing the strongest form of the other person's argument, even if it is not the one they explicitly presented. Creating the strongest form of the opponent's argument may involve ...
In modern usage, a definition is something, typically expressed in words, that attaches a meaning to a word or group of words. The word or group of words that is to be defined is called the definiendum, and the word, group of words, or action that defines it is called the definiens. [6] For example, in the definition "An elephant is a large ...
Biophysical profile. A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [1] with the score being termed Manning's score.[2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications. The "modified biophysical profile" consists of the NST and ...
