Weipike’s siphon system features a rainwater inlet designed based on the Bernoulli equation, developed through rigorous calculations and a specialized design.
The Weipai Ke siphon rainwater inlet separates air from water, creating full-pipe flow conditions within the pipe even when the water level in front of the inlet is very shallow. By utilizing the potential energy generated by the elevation difference as rainwater flows from the roof to the ground, it creates a localized vacuum within the rainwater piping system, thereby inducing a siphon effect that rapidly discharges rainwater to the outdoors.
