Resumo:
The purpose of work is to avaluate the performance of the RAIN-BIRD
QN-14 microsprinkler. In laboratory, the following parameters were considered:
manufacturing coefficient variation, characteristic of equation of discharge vs. pressure.
The manufacturing coefficient of variation was 0.7 %, considered good by ABNT
classification. The discharge vs. pressure data were adjusted through linear regression,
resulting in equation Q = 45,63 H 0,4866 , with 99.98% as determination coefficient (r2).
