Increasing the lateral line length of drip irrigation systems
Aims: The hypothesis of this research is that it is possible to increase the drip irrigation lateral line length by using a larger spacing between emitters at the beginning of the lateral line and a smaller one after a ...
Gotejadores não autocompensantes usando efluente de esgoto tratado para irrigação
This study aimed to evaluate the obstruction of non-pressure compensating emitters using treated sewage effluent (TSE) for irrigation. A drip irrigation system with six models of emitters (encoded) was installed in level ...
Performance of pressure-compensating emitters using treated sewage effluent for irrigation
(Univ Federal Campina Grande, 2016-10-01)
This study aimed to evaluate the flow variation of pressure-compensating emitters using treated sewage effluent (TSE). A drip irrigation system with four types of pressure-compensating emitters (G1 - Naan Dan Jain Model ...
Produção e pós-colheita de duas cultivares de cebola em função da agua no solo
This work aimed at assessing the effect of different water tensions in soil on the development and production of two onion cultivars irrigated by drip system. The experiment was carried out in the experimental area of ...
Variação dos parâmetros físicos, químicos e biológicos da água em um sistema de irrigação localizadaVariation of physical, chemical and biological parameters of water in a trickle irrigation system

Evaluation of heat transfer parameters in packed beds with cocurrent downflow of liquid and gas
(Pergamon-Elsevier Science Ltd, 2001-11)
The results of an experimental investigation on heat transfer from a packed bed with cocurrent gas-liquid downflow to the wall are presented and analyzed in this contribution. The measurements cover the range of operating ...
Hydrogenolysis of glycerol to 1,2-propanediol in a continuous flow trickle bed reactor
(John Wiley & Sons Ltd, 2018-04)
BACKGROUND: Hydrogenolysis of glycerol to glycols in continuous flow three phase reactors is of practical importance due to the need to give value to huge amounts of surplus glycerol. Thermodynamic and kinetic aspects must ...
