Abstract: | Based on theories of critical depth and boundary layer, this paper presents the discharge cofficient of long throated flume with U (circular bottom) shape. The formulation to evaluate relationship between flow depth and discharge is also deduced, whose accuracy satisfies the ISO demand perfectly. |
