Highways and Hierarchies: Ethnographies of Mobility from the Himalaya to the Indian Ocean explores the contemporary proliferation of roads in South Asia and the Tibet-Himalaya region, showing how new infrastructures simultaneously create fresh connections and reinforce existing inequalities. Bringing together ethnographic studies on the social politics of road development and new mobilities in twenty-first-century Asia, this edited collection demonstrates that while new roads generate new forms of hierarchy, older forms of hierarchy are remade and re-established in creative and surprising new ways. Focused on South Asia but speaking to more global phenomena, the chapters collectively reveal how road planning, construction and usage routinely yield a simultaneous reinforcement and disruption of social, political and economic relations.

This book deals with the modeling and simulation of spiral coil heat exchanger, one of the most promising compact heat exchanger. Its design provides the advantages of high turbulence, high heat-transfer coefficients and high fouling resistance. High heat-transfer coefficients allow smaller heat-transfer areas compared to traditional shell-and-tube heat exchangers used for the same duty. This ultimately results in significant size reductions and weight savings as less material is needed to construct the unit.In this book firstly various type of compact heat exchanger used in industries are discussed. After it a brief over view of the research work is presented then modelling and simulation of spiral coil heat exchanger using MS-Excel is done.
