The Calculation on Discharge Capacity of the Porous Pipe

Abstract:

The porous discharge flow tube has been widely used in agriculture, water supply and drainage, ventilation, chemical and other fields. Flow characteristics directly affect the flow uniformity of the porous tube, thereby affecting the efficient use of it. The theoretical analysis and experimental study on the capacity of the porous tube’s discharge (flux of water) have the important project value and theoretical significance. In this paper,the total flow calculation formula is derived by the knowledge of hydraulics, the relation of discharge discount rate is calculated through dimensional analysis and the average single hole discharge formula is established based on some experimental data. The results of the test data and engineering data showed that the formula results and the test results are quite identical.
