Introduction: If the throat velocity exceeds the critical velocity, it is called a standing wave flume or critical depth flume. Standing waves will be formed at the throat of the flame. Since the velocity is critical, the downstream variations in depth do not affect the upstream depth till the submergence ration exceeds 0.7. The standing wave method requires a small movable car at the end of the tube to move a microphone probe inside the tube used to detect the maximum and minimum sound pressure at the specific tone frequency of interest. When the width of the throat (B) is known we can calculate the dischange in the standing wave flume using the formula. Q= 1.7 x Cd x B x H3/2 where Cd= 0.95 to 1.
