Gas pressure and flow formula

1726, Bernoulli discovered the "boundary layer surface effect" through numerous experiments: when the fluid velocity is accelerated. The pressure on the interface between the object and the fluid will decrease, and vice versa. To commemorate this scientist's contribution, this discovery is called "Bernoulli effect". Bernoulli effect is applicable to all fluids, including gas, and it is one of the basic phenomena when the fluid flows stably, reflecting the relationship between the pressure and flow rate of the fluid.

For example, there is a steady flow of fluid in the pipeline, and the height of the liquid column in the vertical open thin tube at different cross sections of the pipeline is different, which shows that in the steady flow, the pressure is small where the velocity is large and the pressure is strong where the velocity is small. This phenomenon is called Bernoulli effect.
