Pipelines can be found by the above formula for wind speed and its internal and external pressure difference is necessarily a linear relationship between the sectional area, and nothing to do with pipelines.

By the above formula may discover the pipeline leaves the wind velocity to send by messenger certain linear relations with the among them external pressure, but has nothing to do with with the pipeline cross-sectional area.

Pipes can be found by the above formula of the wind speed and pressure difference is a measure of the linear relationship between inside and outside, and is independent of the cross-sectional area of pipes.
