The study aims to provide knowledge about the heat transfer characteristics of five different fluids are water, carbon nanofluid, a mixture of ethanol and water, a mixture of methanol and water, a mixture of ethylene glycol and water using a heat exchanger setup which was fabricated for the desired study with the water as the hot fluid in every case studied.This study helps to choose the best coolant out of the tested ones which can be used to cool the components, systems that dissipate heat during its functioning which has to be removed to prevent the failure of the components. Test Section has a cuboidal shell where the hot fluid is filled and copper pipe through which coolant flows. The coolant is circulated and the temperature of the hot fluid in each case is plotted against time on the graph.More the temperature difference better will be the fluid corresponding to that difference as we want more heat to be extracted from hot fluid and losses are neglected as insulation is provided outside shell. As heat is to be dissipated for the proper functioning of components, this forced us to think and research more thoroughly to get in-depth knowledge.

In this book, open flame synthesis has been selected as a method to study the thermodynamic chemical combustion aspect of the formation and growth mechanisms of soot obtained from two domestic fuels commonly and commercially available fuel known as Liquefied Petroleum Gas (LPG) and Biogas to establish the favourable parametric controlled conditions for maximizing the yield of CNTs derived from soot. The presence of MWCNTs was observed under TEM, while surface morphology was viewed under SEM. Mean tube diameter, chirality distribution, constituents of the sample and crystallinity of CNTs were observed under XRPD. Raman Spectroscopy is used to identify the presence of SWCNTs and purity of CNTs. Quality and thermal stability of CNTs has been checked by TGA.

This book examines the evolution, contexts and politics of the structures and institutions that shape contemporary Russia. It analyses the Soviet dissolution, revealing the combination of structural and agency factors. It traces the re-emergence of Russia from a unique perspective that is neither Western nor Eurasian, but specifically Indian, located in the global South. The book looks at key theoretical concepts and practices like democratic centralism that produced an overly centralised and rigid hierarchy within the Communist Party. This book assesses the continuities and changes with the Soviet past and the way the Russian regimes of the past two decades have reinvented and reshaped them. This book provides a multifaceted interpretation of contemporary Russia for general readers and specialists.
