摘要
平行壁面是环形通道当内圆半径趋于无限大时的极限情况 ,流体在矩形通道中流动时所受的内摩擦力或压降是流体在两个平行壁面间流动时产生的内摩擦力或压降的叠加 。
The parallel wall surface is a limit instance of ring shape channel when the inter radius goes to infinity. The inter friction or press drop of fluid flowing in rectangle shape channel is the piling up of that in the two parallel wall surfaces. From the above result, velocity distributing formula and M numerical value of friction modulus is deduced.
