Abstract: A Comprehensive revises on reactive power compensation in transmission line to balanced voltage profile management for safe and economic operation. As we know that voltage instability or voltage sag condition is very much common in today’s fast growing world. In this we study FACTS technology for stable the power system. Mainly we focus on compensation techniques given by the different papers and give a brief review on that which is quite useful in maintaining voltage stability.

Abstract: In the present work an experimental investigation was carried out to study steam flow through a convergent – divergent nozzle. For the tests the geometry of rectangular cross section nozzle were used. The behavior of shock wave was investigated. Different inlet conditions were used at constant back pressure, in the divergent part of the nozzle the shock wave was induced caused instability in the flow.

Keywords: Experimental Investigation, Convergent-Divergent Nozzle.

Abstract: In this research work, brass alloys were produced by sand casting using recycled copper and zinc metals. The zinc content was varied from 10 to 50 wt%. Molten brass in a crucible pot, prefabricated (clay graphite) crucible remains static inside the crucible furnace during the full melting cycle.  This dedicated crucible pot which also act as pouring ladle eliminate inter-alloy contamination. The brass alloys produced from sand casting were subjected to homogenizing annealing heat treatment. Hardness and tensile tests were carried out on the samples from each composition. Also, the samples were subjected to micro-structural investigation using optical microscopy. The results obtained showed that the hardness, yield strength, ultimate tensile strength, percentage elongation and elastic modulus of the alloys increase with increase in zinc content. Also, the micrographs of the samples reveal the presence of a single solid phase which consists of a solid solution of zinc in alpha copper. It was concluded from the study that brass alloys with good mechanical properties can be produced from recycled copper and zinc metals.
