Gaspard de Prony [Lagrange's foundations of the calculus] is assuredly a very interesting part of what one might call purely philosophical study; but when it is a case of making transcendental analysis an instrument of exploration for questions presented by astronomy, marine, geodesy, and the different branches of the science of the engineer, the consideration of the infinitely small leads to the aim in a manner [which is] more felicitous, more prompt, and more immediately adapted to the nature of the questions, and this is why the Leibnizian method has, in general, prevailed in French schools.

document.write(""); PRONY, GASPARD CLAIR FRANCOIS MARIE RICHE DE I-lis career may be studied in Hesiod; in the splendid Prometheus vinctus of Aeschylus, with the scholia; in Heyne’s Apollodorus; in the excursus (I) of SchUzius to the Aeschylean drama, and in the frequently quoted work of Kuhn. The essay of Steinthal may also be examined (Goldziher, Myth. Hebr., Eng. trans., p. 363—392), where the amused student will discover that “ Moses is a Pramanthas,” with much else that is as learned and convincing. See also Tylor’s Early History of Man; Nesfield in Calcutta Review (January, April, 1884); and the article FIRE. (A. L.) PROMOTER, one who promotes (Lat. promovere, to move forward), advances or forwards any scheme, project or undertaking. The most general specific sense in which the word is now used is that of a person who takes the steps necessary to the incorporation of a joint-stock company (see COMPANY) or to the passing of a private or local act of parliament. In legal history, a promoter was one who prosecuted offenders, originally as an officer of the Crown, later as a common informer; the term is still used thus of the prosecutor in a suit in an ecclesiastical court. PRONGBUCK, PRONGHORN, or (in America) simply ANTELOPE, the sole existing representative of a family (Antilocapridae) of hollow-horned ruminants in which the horn-sheaths are forked and annually shed and renewed. Standing about 3 ft. high at the shoulder and slightly more at the croup, the male prongbuck has the black horns rising vertically upwards immediately above the eyes. The general colour is bright sandy fawn, with much white on the face, three white bars on the throat and white under parts and buttocks. The white throat-bands are evidently protective; and the long white hair on the buttocks can be erected and expanded into large chrysanthemum-like bunches as in Japanese deer; these being guides to the members of the herd vJhen in flight. The tail is short; lateral hoofs are wanting; and the teeth are tall-crowned. Female prongbuck produce one or two young at a birth, and are either hornless or furnished with small and more or less rudimentary horns.

20. História Da Equação De Darcy-Weisbach Translate this page Por isto, sua equação teve fraco desempenho comparado com a equação empíricade prony (gaspard Clair Francois Marie Riche de prony, 1755-1839) amplamente http://biosystems.okstate.edu/darcy/Portuguese/HistoriaDarcy-Weisbach.htm

Henry Darcy e sua Lei Glenn Brown Oklahoma State University revised 6/27/00 Traduzido por Luiz Camargo lcamargo@nutecnet.com.br 14/abr/01 h l = fL/D * V onde h l h l = L/D * (aV + bV h l = L/D * [(c + d/D V + (d + e/D)V onde c, d e e são coeficientes empíricos para um dado tipo de tubo. Darcy desta forma introduziduziu o conceito de coeficiente de atrito escalonado por diâmetro; o que nós atualmente chamamos de rugosidade relativa, quando aplicando o Diagrama do Moody. Portanto, é tradicional chamar f de "fator f de Darcy", ainda que Darcy nunca tenha proposto isto naquela fórmula. Os dois conceitos foram juntados por Fanning em 1880 (eu penso). Ele publicou uma compilação dos valores de f como uma função do tipo de tub e da velocidade. Contudo, seria notado que Fanning utilizou o raio hidráulico, ao invés de D na equação do atrito, e assim os valores do "f de Fanning" são apenas 1/4 dos valores do "f de Darcy". A equação de Darcy-Weisbach não foi universalmente proveitosa até o desenvolvimento do diagrama de Moody Christensen, B.A., 2000.
