WebNov 25, 2016 · The reference area is arbitrary in principle, but it is a good idea to choose an area that is characteristic for the object you are considering. As an example, in aircraft aerodynamics we typically use the planform area of the wing as the reference area for both lift and drag coefficients of the wing. WebCalculate the drag coefficient for thecylinder, based on projected frontal area of the cylinder. Consider a circular cylinder in a hypersonic flow, with its axisperpendicular to the flow. Let φ be the angle measured between radiidrawn to the leading edge (the stagnation point) and to any arbitrary pointon the cylinder. how do i know if my incision is infected
