1、計(jì)算管道摩阻：
R=[(λ/D)*(ν^2*γ/2)]*65
=[(0.016/0.3)*(35^2*1.2/2)]*65
=2548Pa
R1=[(λ/D)*(ν^2*γ/2)]*65
=[(0.016/0.15)*(35^2*1.2/2)]*10
=784Pa
2、計(jì)算300mm彎頭摩阻,設(shè)彎頭為90度,且半徑等于300mm,λ查表得0.23：
R2=λ*(ν^2*γ/2)*2
=0.23*(35^2*1.2/2)*2
=338Pa
計(jì)算150mm彎頭摩阻,設(shè)彎頭為90度,且半徑等于150mm,λ查表得0.23：
R3=λ*(ν^2*γ/2)*4
=0.23*(35^2*1.2/2)*4
=676Pa
3、總靜壓：
2548+784+338+676=4346Pa
