The  time required to drain these vessels is known as  efflux time. Draining a liquid from a large storage  vessel through an exit pipe is always associated  with laminar flow in the tank and turbulent flow in  the exit pipe depending on the physical properties  of the liquid and the geometrical characteristics  of the exit piping system. During draining, the  liquid experiences friction and this friction is a  measure of drag. The drag increases many fold when  the flow transforms from laminar flow in the tank  to turbulent flow in the exit pipe. Hence, drag  reduction options are to be explored.  The phenomenon of drag reduction by minute  concentrations of polymer additives has been  attempted for over sixty years, ever since its  discovery by Toms. This book is focused on understanding drag reduction using water soluble  polyacryl amide polymer solutions when a Newtonian liquid ( water in this case) is drained from a cylindrical storage vessel ( Where the flow is essentially laminar) through an exit piping system ( When the flow in the exit pipe is turbulent).\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844393842\"\u003e\u003ch3\u003eModeling\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844393842","offer_id":39497194274909,"sku":"9783844393842","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0f696478-8f4a-4357-8de3-44329146c08f.jpg?v=1757912290","url":"https:\/\/shop.autorenwelt.de\/products\/drag-reduction-using-polymer-solutions-in-gravity-driven-flow-systems-von-subbarao-chirravuri","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
