非惯性参照系下的伯努利方程式的推导

Deduction of Bernoulli equation at non-inertial reference frame

在非惯性参照系下,当某一理想流体作稳定流动时,选取一个任意形状流管,可以推导出其伯努利方程式为12ρv2+(ρgy+axxcos)θ+p=C(常数).利用该方程式可以非常简便地处理流体加速运动问题.

At non-inertial reference frame,when an ideal fluid flows at steady state,select a tube of flow of arbitrary shape,the Bernoulli Equation can be derived as :+.It is very easy to deal with the problem of fluid's accelerated motion.
