अंग्रेज़ी में DRAG COEFFICIENT का क्या अर्थ होता है?
खींचें गुणांक
द्रव गतिशीलता में, ड्रैग गुणांक एक आयाम रहित मात्रा है जिसे द्रव वातावरण में किसी वस्तु के ड्रैग या प्रतिरोध को मापने के लिए उपयोग किया जाता है, जैसे हवा या पानी इसका उपयोग ड्रैग समीकरण में किया जाता है, जहां कम खींचें गुणांक इंगित करता है कि ऑब्जेक्ट में कम वायुगतिकीय या हाइड्रोडायनामिक ड्रैग होगा। खींचें गुणांक हमेशा किसी विशेष सतह क्षेत्र से जुड़ा होता है। किसी भी ऑब्जेक्ट के खींचें गुणांक में द्रव गतिशील खींचने के लिए दो बुनियादी योगदानकर्ताओं के प्रभाव शामिल हैं: त्वचा घर्षण और प्रपत्र खींचें। लिफ्टिंग एयरफ़ोइल या हाइड्रोफ़ोइल के ड्रैग गुणांक में लिफ्ट प्रेरित ड्रैग के प्रभाव भी शामिल हैं। विमान जैसे संपूर्ण संरचना की खींचें गुणांक में हस्तक्षेप खींचें के प्रभाव भी शामिल हैं।
अंग्रेज़ीशब्दकोश में drag coefficient की परिभाषा
शब्दकोश में खींचें गुणांक की परिभाषा चलती द्रव, ईएसपी हवा में किसी ऑब्जेक्ट के ड्रैग का माप है।

Theory of Wing Sections, Including a Summary of Airfoil Data
Ira Herbert Abbott. of minimum drag coefficient with Reynolds number for several
wing sections is shown in Fig. 66. The drag coefficient generally decreases with
increasing Reynolds number up to Reynolds numbers of the order of 20 million.
We assume that the drag coefficient (23) can be expressed as the sum of a
frictional-drag coefficient, depending on the Reynolds number, plus a residual-
drag coefficient which now must depend on the Froude number. Thus, we adopt ...

Wind Loading of Structures
The effect of aspect ratios less than 20 is significant on the effective total drag
coefficient (see Figures 4.10 and 4.19). Other cross-sections may require wind-
tunnel tests to determine drag coefficients. The mean or time-averaged drag force

Engineering Fluid Mechanics
The corresponding result for drag coefficient of a circular cylinder is CD = 87t(1 -
0.87/S2)/S Re, Re < 1, (7.5.4) where S = -0.07721+ In (8/Re). Here the Reynolds
number is based on the cylinder diameter. This result was found byS.
The sharp drop off of the drag coefficient at Re ≈ 3 · 105 is due to the transition of
the previous laminar boundary layer on the sphere to a turbulent boundary layer.
The shear stresses in the turbulent boundary layer are larger, and the outer ...

There is reason to doubt their validity in that they predict a drag coefficient of 0.48
for a Reynolds number of 500 and relative turbulence intensity of 0.07. This is
less than the standard drag coefficient for a sphere at this Reynolds number.
