Abstract: A hydrodynamic model is considered for estimating the angle to be subtended by the spiral portion of high specific speed axial flow water turbine casings. The results are correlated with the ...

Abstract: The soil and water assessment tool (SWAT) has been calibrated and validated to predict stream flow, and to transport sediment and non-point source (NPS) pollutants to the downstream water resources from a small (1,695 ha) ...

Abstract: A porous, packed bed, volumetric solar collector consisting of two dissimilar layers of spherical beads is numerically modeled. The bed is irradiated on the top surface by concentrated solar ...

Abstract: The vortex, the velocity, and the pressure distribution along the vane surfaces are calculated for two impellers, one having six vanes and the other twelve vanes. The vanes were of logarithmic ...

Abstract: The optimum number of vanes for a given centrifugal pump or blower cannot be estimated by Pfleiderer’s equation because of its limitations. In the present investigation, Stodola’s effect is ...

Abstract: Hydrologic models play an important role in the assessment of nonpoint source (NPS) pollution, which is essential for the environmental management of water resources. The present study has been undertaken to evaluate the ...
