Abstract:The irrigation design parameters of punched thin-soft spray tape are studied,such as the hole interval l,flow rate q_m,layout interval B and the maximal laying length L_{max}.The design method of controlling the maximal laying length by using the head loss is discussed.Since the head loss has been defined within 30%,the maximal laying length could be determined by the relationship between head loss and maximal laying length.Two situations are discussed: the flat land and the land on slopes.Finally,two methods,drawing and computerizing,are discussed for the calculation of the maximal laying length.
