resistance of fluid friction

基本解释

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。
It has practical significance to mensurate exactly and effectively for the transmittance coefficient and resistance of fluid friction of plate heat exchanger.
板式换热器的热工特性、阻力特性是选择产品的主要依据，因此准确、高效的测定这两个参数准则具有重要的现实意义。
Viscosity Measure of the resistance to flow, or internal friction, of a fluid. Viscosity changes with temperature so the temperature at which the measurement was made must always be specified.
运动粘度会随温度变化而变化，因此，在给出运动粘度的数值时，通常必须注明其测试温度。
