我们知道,常规管道流量公式为: Q=π/4·D~2·ω·3600 m~3/h (1) 式中:Q—体积流量 m~3/h D—管径 m ω—流速 m/s 利用该公式进行计算因其流速ω通常都是在经验流速范围内取值,故计算出的流量Q会有一定的误差. 对于工作中的管路系统,怎样较为简便地求得管
We know that the conventional pipe flow formula is: Q = π / 4 · D ~ 2 · ω · 3600 m ~ 3 / h (1) where Q- volume flow m ~ 3 / h D- pipe diameter m ω- flow rate m / s Calculation using the formula Because of its velocity ω are usually within the empirical range of flow rate, so the calculated flow Q will be a certain error for the work of the piping system, how to more easily find the tube
