Abstract

The temperature effect of the surrounding environment on mean steady aerial water evaporation in sprinkler irrigation is investigated. An experimental set‐up was designed and built to work at opportune operating conditions holding all the other variables constant to minimise the experimental error. One hundred and thirty‐seven tests were performed for this work, of which 81 were considered valid for a statistical analysis of the data measured. Evaporation ranged from 4.15 to 7.73% as the air temperature varied from 21.0 to 27.0Β° C. Results show a clear dependence of sprinkler water evaporation on air temperature with a logarithmic relation. Further investigations will examine broader temperature intervals to improve the assessment and will consider the effects due to other parameters affecting the phenomenon.

Results are presented of some comparative measurements of air temperature made in spring in 1960 and 1961 in vineyards near Red Cliffs (Victoria) when the soil was subjected to four treatments in separate plots. The treatments used were: (1) Clean cultivation (denoted by O); (2) Rolling (denoted by

The heat and mass transfer equations for a co-flow water spray in air were solved for different combinations of drop diameter category and velocity sub-class, and compared with experimental data. For uniform drop velocities, the number of categories was increased to 10, 50, 100 and 200, as against 5
