The reduction of Fe2O3 powder at the top layer by the volatiles from high volatile (HV) bituminous coal at the bottom layer of a multilayer powder geometry including a separating alumina layer was studied. The simultaneous effects of the alumina layer thickness, time, temperature and the weight of coal on the amount of reduction and coal devolatilization were studied by implementing a rotatable...

The utilization of agricultural machinery represents the main aspect contributing to total energy input in system. trials were achieved using five tractor speeds(3.6, 5.4, 7.2, 9.0 and 10.8 km/hr) tillage depths(10, 15, 20, 25 30 cm) determine implement speed at different depths for 3-bottom disc plough, spring tine cultivator offset harrow on a clay loam soil. design experiment used two factor...

Abstract—The composite flour blend consisting of corn, pearl millet, black gram and wheat bran in the ratio of 80:5:10:5 was taken to prepare the extruded product and their effect on physical properties of extrudate was studied. The extrusion process was conducted in laboratory by using twin screw extruder. The physical characteristics evaluated include lateral expansion, bulk density, water ab...

This paper is concerned with the statistical model development issues, necessary for rapid estimation of the rotor sizing for single main rotor helicopters at the preliminary design stage. However, Central Composite Design (CCD) method, simulation-based data collection, linear regression analysis, mathematical modelsdevelopmentand validations through the analysis of variance (ANOVA) were perfor...

Metal matrix composites, in particular, Aluminium Matrix Composites are gaining increasing attention for applications in aerospace, defence and automobile industries. The use of nonconventional machining techniques in shaping aluminum metal matrix composites has generated considerable interest as the manufacturing of complicated contours such as dies. Electrical discharge machining (EDM) appear...

A power operated maize stalk harvester was designed and developed in the Dept. of Farm Machinery Power Engineering, MPUAT, Udaipur, Rajasthan during 2018-19. The objective this study is to optimize operational parameters harvesting by using RSM techniques. effects independent i.e., blade speed (2000, 4000 6000 rpm) moisture content (38, 42 46%) on cutting efficiency (%) fuel consumption (l/h) w...

Abstract The production of biodiesel from dairy effluent scum using calcined egg shell as the transesterification catalyst has been explored. Eggshell powder was at 900 °C for 3 h and used catalyst. influence methanol-oil molar ratio, concentration reaction temperature were studied Response Surface Methodology employing a Central Composite Rotatable Design. An empirical model that relates yield...
