Energy losses in irregular channels are due only partly to boundary shear and additional energy loss results from the effects of bends, irregularities, and changes in the cross section. Experiments which were designed to clarify some aspects of energy losses in irregular channels are described. It ...

Therefore, state-of-...
In these cases, we also observe a very similar spectral and spatial EELS behaviour, confirming the high transmission of the slot GSP through sharp bends. Figure 3: L-shaped slot resonator. (a) Total EELS signal from the enclosed blue box shown in the inset along with calculations using the...
The elevation of the pump from the ground surface as collected in pump inventory data was added to this. Friction loss is the head loss from resistance in pipe flow (in meters). Friction losses depend upon the type of fluid flow and pipe material. We calculated friction losses considering ...
Figure 2.6 Representation of the power losses at different steps of electric wind energy generation. 2.2.3.1The power coefficient The power coefficient tells how efficient is a turbine capturing the energy contained in the wind. To measure this efficiency, the energy captured by the rotor is ...
Frictional Losses for Noncircular Ducts All friction loss calculations are based on the equivalent hydraulic diameter. With equal length of round and rectangular ducts, constant flow in each duct, and equal resistance to flow in both the round and rectangular ducts, the equivalent round of a rectan...
Thus, resistance losses in cells are equivalent to energy losses; whatever a solar cell loses because of resistance degrades its efficiency. Resistance losses in solar cells occur predominantly in three places: in the bulk of the base material, in the narrow top-surface layer typical of many ...
In the transition buckling mode, structure first deforms stably and then bends unstably with increasing displacement. In the progressive buckling mode, the structure extensively deforms in a stably progressive fashion [124]. Therefore, the progressive folding is generally an ideal deformation mode ...
Pipe losses (changes in section) When a fluid flows through a sharp (sudden) change in the cross section of a pipe, energy is dissipated in the resulting turbulent eddies at the edge of the flow stream, producing a loss of head (or energy per unit weight). If the flow is from a sma...
