摘要
通过牛顿粘滞定律和修正后的伯努利方程对非水平直圆管中黏性流体作层流运动时的流量公式进行了推导。指出将泊肃叶公式中的压强视作广义压强,则文中的推导公式与泊肃叶公式完全一致。说明泊肃叶公式可以用来求解非水平直圆管中黏性流体作层流运动时的流量。本文通过实验验证了推导公式。
According to the Newton’s law of viscosity and modified Bernouli equation,a flow formula of lami-nar flow of viscous fluid in non-horizontal straight round tube is derivate.When the pressure in Poiseuille for-mula is regarded as generalized pressure,the derivation formula is just Poiseuille formula. The derivation formula is proved by experiments.
