摘要
The drain gutter (20) has an open flow duct coupled at one end to an outflow. As the water flows out, the water level (11) falls in the direction of the outlet so that the outflow (Q) is limited by the actual cross-sectional area of the flow at the outlet. The rate of outflow can be increased, or the same rate of outflow can be achieved with a gutter of smaller cross-sectional area, by installing a pipeline (21) underneath the gutter. The pipeline is connected to a hole in the floor of the gutter at a point midway along its length, and extends to the gutter outlet. ADVANTAGE - Low-cost design given drain effect.
