resistance of fluid friction

常見例句

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(huì)同時(shí)伴隨產(chǎn)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(xiàng)損失的計(jì)算誤差。
It has practical significance to mensurate exactly and effectively for the transmittance coefficient and resistance of fluid friction of plate heat exchanger.
板式換熱器的熱工特性、阻力特性是選擇產(chǎn)品的主要依據(jù)，因此準(zhǔn)確、高效的測(cè)定這兩個(gè)參數(shù)準(zhǔn)則具有重要的現(xiàn)實(shí)意義。
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.
運(yùn)動(dòng)粘度會(huì)隨溫度變化而變化，因此，在給出運(yùn)動(dòng)粘度的數(shù)值時(shí)，通常必須注明其測(cè)試溫度。
