Web3 jul. 2007 · For example, say you have a 100 mm diameter object that must be reduced to 10 mm diameter. If you do it in one step, the reduction ratio is A 0 /A f = 100 2 /10 2 = 100. If you do it in two steps (100 to 50 and 50 to 10), then you get reductions of 4 (100 2 /50 2) and 25 (50 2 /10 2 ), which must be multiplied to get the same value as you do ...

What Is Length-to-diameter Ratio (L/D)? - Stanford Magnets

WebIn aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions. The L/D ratio for any given body will vary according to these flight conditions Webhigh speed forging of circular discs of large slenderness ratio i.e. l=D(where l D height of the preform and D D its diameter). Moreover, interest in high speed has grown considerably because of the introduction of new and fast deformation processes.
