則沿程損失大；還與流速的平方值成正比關(guān)系。當(dāng)然計(jì)算比較繁瑣，簡單的方法可以估算。管路局部損失是水流在管道中流過底閥、閥門、彎頭、異徑管等配件過程中，由于局部裝置使流型變化；流速方向和大小都改變，而且在流動(dòng)中出現(xiàn)漩渦，使水流互相碰撞、沖擊。這種局部阻力而引起的水力損失叫做局部損失。局部損失的大小與流過管道配件處的水流速度平方值成正比，同時(shí)，也與配件的形狀和數(shù)量有關(guān)。配件斷面形狀變化大，數(shù)量多，則局部損失就愈大。當(dāng)管路布置方案確定以后，一般都要經(jīng)過計(jì)算方法求得管路損失揚(yáng)程，然后確定水泵站的設(shè)計(jì)揚(yáng)程，才能進(jìn)行水泵選型。</span>

在工程上，我們必須要計(jì)算知道它的數(shù)量多少，才能正確地選用水泵，確定所需要的水泵揚(yáng)程。管路沿程損失是發(fā)生在水流的全部流程上的摩擦阻力，它與管壁粗糙度、管長、管徑、流速等有關(guān)，根據(jù)水力學(xué)原理，可以建立它的關(guān)系式。沿程損失與管壁粗糙度有關(guān)的沿程摩擦系數(shù)成正比關(guān)系，不同的管材其粗糙度不同，鑄鐵管比較粗糙，沿程摩擦系數(shù)就大些；塑料管比較光滑，沿程摩擦系數(shù)就小些。與管子長度成正比關(guān)系；與管徑成反比關(guān)系，就是說，當(dāng)流量一定時(shí)，管徑小、流速快。
