Irrigation means the artificial supply of water to the crop for its better crop growth sown in the field. India is one of the important countries in the production of agricultural commodities. The present population of India is increasing day by day and it is more than 1300 million. Porous pipe is useful both for surface and subsurface micro irrigation systems and it can be used in a variety of ways to meet any irrigation need. It is not the rain which is reproduced but its direct effect upon the plants in the form of soil moisture which also supplies nutrients when it is buried, not only this a good amount of irrigation water which otherwise would be lost to evaporation and deep percolation will be saved. To analyse the hydraulic characteristics of porous pipes by studying pressure-discharge relationship, head loss under low pressure head variation. To develop the pressure discharge relationship of porous pipe. The present study was undertaken through experiment in an open porous pipe.
