← ScienceWhich distortion results when turbulent flow assumption inappropriately used?
A)Increased calculated pressure drop downstream
B)Underestimated particle settling velocity
C)Increased effective fluid density value
D)Underestimated drag around an airfoil✓
💡 Explanation
The inaccurate flow assumption reduces calculated velocity due to an underestimation regarding energy transfers within the turbulent eddy viscosity; therefore, the drag is underestimated, rather than other volumetric properties, because these are calculated independently of macroscopic flow.
