The shape and size of each branch and the state of suction are the same. If the volume of suction is equal, the calculated static pressure of each branch is equal. If the residual static pressure at the junction point is equal, the suction capacity of each branch is equal. This is the so-called static pressure constant principle. If the remaining static pressure of the dry pipe flow to the confluence point is not only equal, it is equal to the static pressure of each branch pipe, then the suction volume of each branch is not only equal, but also can absorb the wind according to the given air volume. This is the principle of uniform suction.

As far as the general situation is concerned, for a branch with arbitrary shape and size and any given volume of wind, as long as the static pressure of each branch is calculated and the remaining static pressure of the air flow to the junction point is equal to the calculated static pressure of the branch, the pipe can absorb the wind according to the given air volume, this is the principle of quantitative air suction。 It is more universal for the design of the suction pipe。
