Abstract：The dripper design operation pressure is determined by two grades optimal method and Powell optimal method.First of all,diameter of lateral and the dripper design operation pressure are viewed as deciding variable and diameter of lateral and the dripper design operation pressure are computed by Powell optimal method.Then,lateral with standard diameter which was not below to original optimal diameter and limited pressure is not below to original optimal maximum pressure is selected.The dripper design operation pressure,which could be applied to drip irrigation design,is determined.
