As there is justification showing that Poiseuille's Law is not suited for vertical Capillary tube viscometer, Poiseuille's Law has not been used to deduce the calculation formula for measuring liquid viscosity by means of vertical Capillary tube viscometer; it can only be used to deduce the calculation formula for measuring liquid viscosity by horizontal capillary tube viscometer. In this article, we explained the extension of Poiseuille's Law to deduce the Calculation formula for measuring liquid viscosity by using shallow pool and deep pool Capillar tube viscometer, and so corrected the mistakes in using Poiseuille's Law for a long time.
由于有理由表明泊肃叶定律不适用于垂直毛细管粘度计，所以并未用泊肃叶定律来推导通过垂直毛细管粘度计测量液体粘度的计算公式；它仅用于推导通过水平毛细管粘度计测量液体粘度的计算公式。在本文中，我们阐述了泊肃叶定律的扩展，以推导使用浅池和深池毛细管粘度计测量液体粘度的计算公式，从而纠正了长期以来在使用泊肃叶定律时所存在的错误。
