- (b) Bathroom sinks and some other fixtures include an overflow opening in the basin. This opening is located on the wall and near the top of the basin. The overflow opening serves two important functions: If the water tap is left on while the drain stopper is closed, the opening will channel water down into the drain opening rather than letting is spill out of the sink onto the floor. The overflow allows the sink to drain faster by introducing air into the system. A sink with a dimension given in Figure Q2(b), has water flows into it at a rate of 8 L/min. If the drain stopper is closed and water level in the sink remains constant, determine the average velocity of water flows through the 3.0 cm diameter overflow hole.
