Analysis of Losses in Hydraulic Turbines
1996The paper gives a brief discussion on the influence of the different losses in a hydraulic turbine. Of special interest are the friction losses which decreases with Re. This leads to a scale up of the turbine efficiency from model to prototype as expressed in the IEC code according to the theory by prof. Spurk [1].

Hydraulic Loss of Finite Length Dividing Junctions
Journal of Fluids Engineering, 2017A general hydraulic loss coefficient correlation for perpendicular, cylindrical, finite length dividing pipe junctions is developed and implemented in a discrete dividing-flow manifold model. Dividing-flow manifolds are used in several technical appliances, e.g., in water and wastewater treatment, swimming pool technology, air engineering, and polymer ...

Long-term sealing loss of hydraulic bearings
Russian Engineering Research, 2011The factors responsible for the loss of sealing of hydraulic bearings in long-term operation are considered. The appearance of cavitation zones in the working fluid of hydraulic bearings and microscopic hydraulic bearings is explained.

Evaluating hydraulic losses in FRKDI bag filters
Chemical and Petroleum Engineering, 1987Methods for evaluating and reducing the hydraulic resistance and optimizing the power consumption of FRKDI filters were assessed. Hydraulic losses were calculated by determining local hydraulic resistances along the gas flow from the inlet to the outlet of the filter and summing these values.

Hydraulic Losses - How to Determine - How to Use
SPE Permian Basin Oil Recovery Conference, 1959Permian Basin Oil Recovery Conference, 7–8 May, Midland, Texas Abstract The factors which affect the treatment cost of an oil or gas well are numerous. These factors, hydraulic hp, treating fluid, well equipment, etc., may be determined and controlled prior to the treatment. An engineering design of a

Hydraulic losses of a gearbox: CFD analysis and experiments
Tribology International, 2013Abstract Efficiency is becoming a main concern in the design of power transmissions. It is therefore important, especially during the design phase, to have appropriate models to predict the power losses. For this reason CFD (computational fluid dynamics) simulations were performed in order to understand the influence of geometrical and operating ...

Thermodynamic Determination of Power Loss in Hydraulic Components
Journal of Fluids Engineering, 1973The theory of a method, based on thermodynamics, for determining the power loss in hydraulic components is described. An experimental investigation of the method has been carried out on a hydrostatic pump with encouraging results. The major advantages of the method are that the measurements are simple and that no knowledge of the rate of flow or the ...

Fluid Loss from Hydraulically Induced Fractures
Journal of Petroleum Technology, 1970Dynamic fluid loss tests provide the best method for simulating the fluid loss process during hydraulic fracturing. Through the use of these tests and a reasonable theoretical model for the rate of fracture growth, fracture length can be predicted with acceptable accuracy.
