Abstract The main purpose of this study is investigation of hydraulic properties in drip irrigation tape, in this study, 10 type of drip irrigation tape, were tested, and was investigated 4 Effect of temperature water containing 13, 23, 33 and 43 ° C according to the standard ISO 9261 and ISO IRISI Initially all experiments were performed in standard temperature (23°C) in order to find a irrigation tapes. The obtained results are as follows: According to the Cv8 models tapes were ranked as good and 2 models as medium, According to the difference of between the actual and nominal flow rates 3 models were ranked as good, 3 models as medium, 3 models acceptable and 2 models was unacceptable, According to the EU, 9 models were ranked as excellent and T3 was ranked as good, According to the UC, all of models UC were more than 70% and their flow rate variation follows normal distribution, According to qvar, flow rate changes in 3 models were acceptable, 2 models were ranked as good and 5 models were unacceptable.
