Coeficientes de perda de carga em valvulas e acessorios no escoamento laminar de fluidos nao-Newtonianos
(2000-01-01)
Friction loss coefficients for laminar flow of xantan gum solutions (concentrations in the range of 0.1-0.5% by weight) through valves and fittings were experimentally determined. The rheological behavior, studied by means ...
Diffusion coefficients during osmotic dehydration of tomatoes in ternary solutions

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 ...
Friction losses in valves and fittings for viscoplastic fluids

Optimizing Inventory and Yield Data Collection for Forest Management Planning
(OXFORD UNIV PRESS INC, 2010)
This work uses a Cost+Loss approach to estimate the optimal investment in inventory information for forest planning A bootstrapping approach is used to simulate the impact of different inventory intensities on the quality ...
Network reconfiguration and loss allocation in a deregulated environment of distribution systems
(2005-12-14)
Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality ...
On the Steinmetz hysteresis law
(ELSEVIER SCIENCE BV, 2008)
The behavior of the Steinmetz coefficient has been described for several different materials: steels with 3.2% Si and 6.5% Si, MnZn ferrite and Ni-Fe alloys. It is shown that, for steels, the Steinmetz law achieves R(2)> ...
