RESUMEN
Modern aluminium composites reinforced with variety of hard particles become more usage in Industrial environment. But manufacturing of composites with homogenously distributed reinforcement becomes the challenge. To overcome this challenge, most of the Aluminium composite are undergone a secondary extrusion process. The data presented here are related to hot extrusion of round geometry to hexagonal section Al/B4C composite. Availability of data is extended to expose the optimal parameters of the process over the extrusion load and tensile strength of the extrudate. Ram speed, geometry of die profile, billet temperature and friction within the die and billet interface have been considered as chief process parameters which influence the extrusion load and strength of the product. Totally, nine experiments were conducted as per Taguchi's L9 orthogonal array to reach optimal parameters. Most influencing parameters with ranking significance have been arrived through ANOVA, MRPI and grey grade. Optimal parameters were compared with confirmation experiments and predicted one to justify the investigation.
RESUMEN
This paper focuses on estimation of available solar radiation from sunshine hour duration. Sunshine hour duration data from 2013 to 2017 G.C recording from Adama metrology agency, average daily global radiation in horizontal and tilt surface for global, diffuse and beam radiation are calculated also hourly global radiation and diffuse radiation data are calculated in tilt surface reach. Finally global and diffuse radiation data for January 5, 2017 and July 5, 2017 are calculated.
