Abstract

The discharge measurement is significant in wide engineering applications such as water conveyance, sewer system, irrigation, and drainage system. Many devices are designed to measure discharge in partially filled circular and semicircular channels. In this study new semicircular mobile flume depends on the concept of developing a contracted zone to have a control section was examined. The contraction was made by installing a vertical pipe with axial holes at the semicircular open channel to create critical flow. To evaluate the efficiency of this type of devices mathematical and experimental studies were presented. Specific energy, discharge, and Froude number equations were used to deduce the mathematical model. Experimental work was carried out in measuring the discharge values with known specific energy values. The experimental data was used to evaluate the mobile device to measure discharge. New equations for both discharge and discharge coefficient were presented. The verification leaded to have a discharge correction equation to calculate the discharge based on the contraction ratio and the measured water depth in the vertical pipe. Results of the comparison showed that the proposed model provided a reliable prediction of the discharge with high accuracy and maximum error up to 8.7%.
