{"product_id":"2940156797189","title":"Drag coefficient","description":"In fluid dynamics, the drag coefficient (commonly denoted as: C d {\\displaystyle \\scriptstyle C_{\\mathrm {d} }\\,}, C x {\\displaystyle \\scriptstyle C_{\\mathrm {x} }\\,} or C w {\\displaystyle \\scriptstyle C_{\\mathrm {w} }\\,}) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area.","brand":"Euprint press Limited","offers":[{"title":"Default Title","offer_id":47114642489584,"sku":"2940156797189","price":1.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940156797189_p0.jpg?v=1764087077","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940156797189","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
