Jurin's law describes the rise and fall of a liquid within a thin capillary tube. Named after its discoverer James Jurin. This law is expressed as: where * ''h'' is the liquid height ; * ''γ'' is the liquid surface tension ; * ''θ'' is the contact angle of the liquid on the tube wall ; * ''ρ'' is the liquid density ; * ''r'' is the tube radius ; * ''g'' is the gravitational acceleration. This law is valid if the tube radius is smaller than the capillary length. ==See also== * Capillary action 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「Jurin's law」の詳細全文を読む スポンサード リンク
