This book was developed with the aim of analysing the hydraulic situation of a drip hose from a rural property after 6 and 12 months of use. The experiment was conducted in a protected environment belonging to the Irrigation and Drainage Engineering Laboratory (LEID) of the Federal University of Campina Grande (UFCG), located in the municipality of Campina Grande - PB. The response of the emitters was analysed when they were subjected to five different service pressures (PS) (30, 50, 70, 90 and 110 kPa) and the use of phosphoric acid (H3PO4) as a corrective agent for unclogging, in six different dosages, based on the methodology proposed by Almeida (2010). The average flow rate, Coefficient of Uniformity of Application (CUD), Coefficient of Flow Variation (CVq) and Degree of Clogging (GE) were assessed.
