A section of plastic pipe is arranged at the outlet of the tap water pipe, and a plurality of small holes are arranged around the plastic pipe. Can water flow out of the small hole?
Relating to site conditions. Relating to the velocity and pressure of water in the pipe. When conditions are appropriate, a venturi effect is produced under the condition that the flow rate is large and the outlet is unobstructed, and the water will not flow out of the small hole.
When the pressure is lower than the atmospheric pressure, the inhalation of air will occur. The venturi effect is the low pressure suction caused by the increase of the velocity of the fluid (air).
On the basis of fluid mechanics (Bernoulli) "Bernoulli's law", in a continuous flow fixed, when the fluid velocity increases, the fluid pressure drop
