fluid head loss

基本解釋

While flowing through a pipe, the fluid is subjected to the loss of head due to the friction of the inner surface of the pipe against it.
流體流經(jīng)管道時，由于管道表面的摩擦力而產生力頭損失。

However, For pipes with local resistance loss, the friction head loss caused by the viscosity of fluid does exist, which may lead to the calculation error.
但是在形成局部阻力損失的管段中，還會同時伴隨產生由于液體的粘性力引起的漩程水頭損失，這就造成了這項損失的計算誤差。
According to current engineering hydrodynamics, there's positively constant head loss in Bernoulli's theorem for identical stream line in viscous fluid, which can later turn into heat and dissipate.
現(xiàn)行工程流體力學與水力學理論通常認為粘性流體元流伯努利方程中的水頭損失項是恒正的，并且這部分損失的機械能轉變?yōu)闊岫纳⒌袅恕?/li>
