3) 系统实验性计算的模仿:
The total airflow or the system resistance curve can be measured using the experimental method. In this method, the operating airflow is obtained when the engineer superimpose the airflow and system resistance curve.
不考虑如何运作,产生自系统的气流,以下所示的系统阻抗曲线表示了所有系统
如下表示的是:非线性气流对比静电压:
DP = KrGN
Where,
DP = 系统压力损失
K = 系统的负载因素
r = 空气密度
G = 气流比率
N = 恒量,在1和2之间变化
如N=1,气流是薄的。
如N=2,气流是紊乱的。
