One of the major parameters of a hydraulic machine is its energy intensity, i.e. its power/output ratio. This article presents the results of theoretical studies of the effects of additional head loss of transporting fluid through helically coiled flexible pipe on specific energy consumption of fertigation machinery and pipeline transport. Computational methods have been used to determine that pressure loss will be 15-20% higher on the average than the loss at a straight section, depending on the average radius of coil helix/design pipe diameter ratio. Correlations have been obtained that allow for justification of major mobile fertilizer system parameters based on the need to minimize pressure loss.

Vibration Rate

The article discusses the results of theoretical studies of vibrations of a plastic grate on elastic supports of a coarse litter cleaner under accidental exposure to raw cotton. Graphical dependences of changes in displacements and vibration rate of the grate on changes in the coefficients of stiffness, dissipation and on the disturbing load from raw cotton at various values of the grate mass are constructed. Based on the analysis of the obtained graphical dependencies, the values of the system parameters are recommended. KEYWORDS: plastic grates, elastic supports, raw cotton, plastic pipes, mass, polyethylene, stiffness coefficient.

Abstract.Recent photometric and spectroscopic observations of the dwarf nova system Z Cha are discussed. Methods for constraining the system parameters are applied and the disc emissivity is deduced as a function of radius. Indications are found that the disc shrinks in size with increasing time after outburst.
