Short Summary

This study investigates the impact of water temperature on pressure-compensating (PC) and turbulent-flow (T) drip emitters under controlled laboratory conditions. The findings show that water temperature significantly affects emitter discharge and hydraulic performance.

Objective

• Investigate the effects of water temperature on PC and T drip emitters

Study Configuration

• Spatial Scale: Laboratory-scale experiments
• Temporal Scale: Short-term experiments (hours to days)

Methodology and Data

• Models used: Linear mixed-effects models (LMM) and nonlinear regression
• Data sources: Experimental data collected in a laboratory setting, following UNE-EN ISO 9261:2010 procedures

Main Results

• Water temperature significantly affects emitter discharge, with contrasting responses between PC and T emitters.
• Temperature influences the pressure-discharge parameters k and x, particularly in PC emitters.
• Hysteresis during pressure ramp cycles was observed only in PC emitters.

Contributions

• This study provides new insights into the effects of water temperature on drip irrigation emitter performance, highlighting the need to consider thermal variability in system design and evaluation.

Funding

• This research was funded by the Spanish Ministry of Science and Innovation (project code: RTI2018-102013-B-I00) and the Generalitat Valenciana (project code: PROMETEO/2020/173).
