fluid head loss

常见例句

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.
流体流经管道时，由于管道表面的摩擦力而产生力头损失。

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损失的管段中，还会同时伴随产生由于液体的粘性力引起的漩程水头损失，这就造成了这项损失的计算误差。
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.
现行工程流体力学与水力学理论通常认为粘性流体元流伯努利方程中的水头损失项是恒正的，并且这部分损失的机械能转变为热而耗散掉了。
