The study was conducted by designing new  stilling basin models in a rectangular shaped pipe outlet of size 10.8cm x 6.3 cm with  three inflow  Froude numbers  namely, Fr = 1.85, 2.85 and 3.85.  To study the scour pattern downstream of stilling basin, total 33 test runs were conducted using same test run time and sand bed material. The scour pattern (depth and location) after the end sill were measured for each test run.  The study indicates that there is a significant effect of the shape of the end sill geometry on the reduction of scour depth downstream of end sill for the pipe outlet stilling basin.  <#LINE#> @ @  Alikhani A., Behrozi Rad R., Fathi Moghadam, Hydraulic Jump in Stilling Basin with Vertical End Sill.

<#LINE#>Synthesis and Characterization of Soybean Oil Based Biodiesel under Optimal Sonication Power<#LINE#>K.L.@Konge,A.S.@Sabnis<#LINE#>26-32<#LINE#>5.ISCA-RJEngS-2013-089.pdf<#LINE#> Department of Polymer and Surface Engineering, Institute of Chemical Technology, Nathalal Parekh Marg, Matunga (E), Mumbai, INDIA <#LINE#>1/7/2013<#LINE#>10/7/2013<#LINE#>  Biodiesel is gaining more and more importance due to depletion and uncontrollable rates of fuel resources. Biodiesel is a renewable, biodegradable and nontoxic fuel. The use of vegetable oils and their derivatives as alternative for diesel fuel is the best solution in the current scenario. Nowadays economical processes to save the energy and to reduce experimental cost plays very important role in biodiesel production. The present study employed simultaneous application of sonic and mechanical energy to assist transesterification of soybean oil. The objective was to optimize the sonication power to achieve the highest possible yield of methyl ester of soybean oil. Experimental results showed that the optimized reaction conditions involved oil to methanol molar ratio 1:6, sonication power 210 W, catalyst concentration 0.2 wt% of oil and mechanical agitation speed 200-300 rpm at 45 C to yield the soybean oil methyl ester (SOME) up to ~95% yield in 60 minutes. Further, the synthesized SOME was characterized for density, kinematic viscosity, acid number, cetane number, calorific value, flash point, distillation temperature, sulfated ash content, carbon residue and fatty acid composition according to ASTM standards to ensure the quality of SOME to act as biodiesel. <#LINE#> @ @ Gerhard K., Dunn R.O. and Bagby M.O., Biodiesel fuel: The use of vegetables oils and their derivatives asalternative diesel fuel, available from, http://journeyforever.org/biofuel_library/VegetableOilsKnothe.pdf.

This paper offers a detailed picture of radial type vane profile design procedure based on fundamental understanding of published procedures. There are limited numbers of published vane profile design procedures which generally lack the explanation and detailed step by step procedure available for designers to systematically design and develop radial type vane profile, so the designers are forced to reverse engineer the vane profiles popularly available in the market. In the case of published procedures great problem arises while following them since some of them are contradictory to each other. In this paper while designing the vane profile, the overall dimensions of an existing impeller were not changed. Commercial 3D CAD software is used to create the 3D model. This approach will encourage the designers to enhance the performance of existing as well as new models of pumps.  <#LINE#> @ @  Church G., Centrifugal pumps and Blowers, Wiley, New York (1944) @No $ @ @  Pfleiderer C., Die Kreiselpumpen, Springer-Verlag, Berlin (1961) @No $ @ @  Balge O.E., A Study on Design Criteria and Matching of Turbomachinery, ASME Journal of Engineering for Power, January, 83-102, 103-114 (1962) @No $ @ @  Stepanoff A.J., Centrifugal and Axial Flow Pumps, Krieger Pub.

Finite element analysis is used to determine the stress intensity factor and the simulation is performed on specimens with various crack-length to specimen-width (a/W) ratios. The software used for the analysis is APDL 12.1[ANSYS]. The reliability of the software has been proven using SENB specimen as the benchmark problem. The stress intensity factors are presented and observed along the crack front for different a/W ratios. The stress intensity factor is found to have the maximum value at the edges along the crack front and minimum at the midplane for different a/W ratios. <#LINE#> @ @ Chaitanya G., Srinivas K.and Kumar J.
