In fluid dynamics, the reyn is a British unit of dynamic viscosity, named in honour of Osbourne Reynolds, for whom the Reynolds number is also named.〔Juvinal, Robert C. & Marshek, Kurt M.; ''Fundamentals of machine component design''. 2nd ed., 1991, pp. 480, ISBN 0-471-62281-8〕 ==Conversions== :1 reyn = 1 lbf·sec·inches−2 The relation between reyn and centipoise is approximately: :1 reyn = 6.89476 × 10 6 centipoise In SI units, viscosity is expressed as newton-seconds per square meter, or pascal-seconds. The conversion factor between the two is the same for stress: :1 reyn = 6890 Pa × s 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Reyn」の詳細全文を読む スポンサード リンク
