GEOMETRIC INDEX AND LOCAL HEAD LOSS IN CONNECTION OF ONLINE EMITTERS
(Soc Brasil Engenharia Agricola, 2014-11-01)
The objective of this research is to present a study on a relationship between the local head loss in connection of emitters in pipes with different diameters used in drip irrigation, with the online geometry of the emitter ...
LOCAL HEAD LOSS OF NON-COAXIAL EMITTERS INSERTED IN POLYETHYLENE PIPE
(AMER SOC AGRICULTURAL & BIOLOGICAL ENGINEERS, 2009)
The design of a lateral line for drip irrigation requires accurate evaluation of head losses in not only the pipe but in the emitters as well. A procedure was developed to determine localized head losses within the emitters ...
Perda de carga em microtubos e conectores utilizados em microaspersão
(Associação Brasileira de Engenharia Agrícola, 2009)
Este trabalho foi desenvolvido com o objetivo de ajustar equações que estimam a perda distribuída de carga em microtubos utilizados em microaspersão e a perda localizada de carga na passagem lateral do fluxo por meio dos ...
Perda de carga em mangueiras gotejadoras novas e usadas
(2011-12-19)
This paper aims to determine the importance of emitter ́s local head loss in the hydraulic design of hose drip lines, as well as comparing the result of equations that calculate the local head loss; besides verifying the ...

Head loss in screen and disc filters using a data acquisition system
(Empresa Brasil Pesq AgropecBrasiliaBrasil, 1995)
Loss of imprinting and loss of heterozygosity on 11p15.5 in head and neck squamous cell carcinomas
(Wiley-Blackwell, 2001-10-01)
Background. IGF2 and H19 are reciprocal imprinted genes with paternal and maternal monoallelic expression, respectively. This is interesting, because IGF2 is known as a growth factor, and H19 encodes a RNA with putative ...
