在解决风流运动问题时利用伯诺里方程式: P_1-P_2+ρ_1gH_1-ρ_2gH_2+κ_1(υ_1~2ρ_1)/2- -κ_2(υ_2~2_ρ2)/2=h_(rp) (1) 式中:P_1及P_2——风流始端及末端的压力;ρ_1及ρ_2——风流始端及末端的空气密度;g——自由落体加速度;H_1及H_2——空气柱的高度;υ_1及υ_2——风流在始端及末端处的流速;κ_1及κ_2——表征截面内风速分布的不
In the solution to the problem of wind movement using the Bernoulli equation: P_1-P_2 + ρ_1gH_1-ρ_2gH_2 + κ_1 (υ_1 ~ 2ρ_1) / 2- -κ_2 (υ_2 ~ 2_ρ2) / 2 = h_ (rp) And P_2 - pressure at the beginning and end of the wind flow; ρ_1 and ρ_2 - air density at the beginning and end of the wind flow; g - acceleration of the free-fall body; H_1 and H_2 - the height of the air column; υ_1 and υ_2 - Velocity at the tip; κ_1 and κ_2 - characterize the distribution of wind velocity across the cross section
