Characterization of Hydraulic Power in Free-Stream Installations
International Journal of Rotating Machinery, 2017 The performance of open-channel hydropower devices can be optimized by maximizing the product of their load, hydraulic, and generator efficiencies. The maximum hydraulic power theoretically available must be defined according to the operational scenario ...

OVERVIEW OF SELECTED HYDRAULIC DEVICES SUPPORTING ROAD RESCUE OPERATIONS
Journal of Science of the Gen. Tadeusz Kosciuszko Military Academy of Land Forces, 2017 The intense human activity determines the continuous development of systems and means of transport, which contributes to the intensification of existing road traffic risks and the emergence of new ones. Reduction in the number of fatalities of road accidents is dependent on investment in transport infrastructure, the development of safety sys-tems for ...

Hydraulic Modeling of a Mixed Water Level Control Hydromechanical Gate [PDF]
, 2011 This article describes the hydraulic behavior of a mixed water level control hydromechanical gate present in several irrigation canals. The automatic gate is termed "mixed" because it can hold either the upstream water level or the downstream water level

Gіrnichі, budіvelnі, dorozhnі ta melіorativnі mashini, 2019 На сьогоднішній день зберігається тенденція використання землерийної техніки зі змінними робочими органами. З точки зору технології виконання робіт це має економічно доцільне обґрунтування [1]. Проте, якщо розглядати довговічність окремих вузлів машини, така експлуатація базової машини призводить до різкого зменшення її довговічності та погіршення ...
