| Abstract: | The new equation for friction loss along the plastics pipe of micro irrigation is presented using the multi regression analysis according to existing friction equation Also,such factors as pipe diameters,flow and water temperatures,etc,are taken into account in the equation,thus making calculated results adaptable to practice.Accordingly,the equation is considered to meet the design requirements and to be used in the design and calculation of micro irrigation engineering through analysis. |
