Washburn Equation


Washburn Equation
 Washburn Equation
 Уравнение Уошбурна
  Описывает капиллярное течение жидкости в пористых материалах. Получено для случая цилиндрических капилляров в отсутствие поля силы тяжести. L2 = γDt/4η, где t – время, за которое жидкость с вязкостью η и поверхностным натяжением γ проникает в полностью смачиваемый, пористый материал со средним диаметром пор D на расстояние L.
