A study on the comparison of kinetic energies calculated with some formulas using Fulljet nozzle

Abstract

Objective: The objective of this study was to compare kinetic energies calculated by different formulas with Rose’s (reference) formula, using Fulljet type nozzle (½ HH-50 WSQ) at different pressures. Material and Methods: A platform in the dimension of 1x1 m was used to place 17 cups (250 cm3) and inclined at a slope of 9%. Then, artificial rainfalls (at pressures of 30, 40, 50, 60 and 70 kPa) was applied with a ½ HH-50 WSQ nozzle for 5 minutes and each experiment was triplicated. Drop diameter, rainfall intensities, terminal velocities were determined and kinetic energies were calculated with different equations. Results: In this study, it was found that rain intensities varied between 85- and 109 mm h-1, Christiansen coefficients (CU) (%) were 83-87 %, drop diameter (D50) were 1.77-2.05 mm, and terminal velocities were 6.08-6.67 m s-1. Average kinetic energies were also calculated between 9.94-46.59 J m-2 mm-1, respectively. Conclusions: The results obtained from this study (±5 %) were found to be in good agreement with the Rose (1960) formula and some kinetic energy formulas.

Fulljet başlık kullanılarak bazı formüllerle hesaplanan kinetik enerjilerin karşılaştırılması üzerine bir çalışma

Abstract

Amaç: Farklı basınçlarda Fulljet tipi başlık (½ HH-50 WSQ) kullanılarak Rose (referans) formülü ile farklı formüllerle hesaplanan kinetik enerjilerin karşılaştırılması amaçlanmıştır. Materyal ve Yöntem: %9 eğimli 1x1 m boyutunda platform üzerine 17 adet kap (250 cm3) yerleştirilmiştir. Daha sonra bu kaplara 5 dakika sürede yapay yağışlar (30, 40, 50, 60 ve 70 kPa basınçlarda), ½ HH-50 WSQ başlık ile 3 tekrarlı olarak uygulanmıştır. Damla çapı, yağış şiddetleri, terminal hızlar belirlenmiş ve kinetik enerjiler farklı eşitliklerle hesaplanmıştır. Araştırma Bulguları: Bu çalışmada yağış şiddetleri, 85-109 mm h-1, Christiansen katsayıları (CU) (%) %83-87, damla çapları (D50) 1.77-2.05 mm ve terminal hızlar 6.08-6.67 m s-1 belirlenmiştir. Ortalama kinetik enerjiler de sırasıyla 9.94-46.59 J m-2 mm-1 arasında hesaplanmıştır. Sonuç: Bu çalışmada, Rose (1960) formülü ile bazı kinetik enerji formülleri arasında çok yakın (%±5) ilişkiler bulunmuştur.
