Did you know?
A streamlined body looks like a fish ( Tuna ), Oropesa, etc. or an airfoil with small angle of attack, whereas a blunt body looks like a brick, a cylinder or an airfoil with high angle of attack. For a given frontal area and velocity, a streamlined body will have lower resistance than a blunt body. See more In fluid dynamics, the drag coefficient (commonly denoted as: $${\displaystyle c_{\mathrm {d} }}$$, $${\displaystyle c_{x}}$$ or $${\displaystyle c_{\rm {w}}}$$) is a dimensionless quantity that is used to quantify the See more The drag equation $${\displaystyle F_{\rm {d}}={\tfrac {1}{2}}\rho u^{2}c_{\rm {d}}A}$$ is essentially a statement that the drag force on any object is proportional to the density of the fluid and proportional to the square of the relative See more Concept The force between a fluid and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction … See more The drag coefficient $${\displaystyle c_{\mathrm {d} }}$$ is defined as where: • $${\displaystyle F_{\mathrm {d} }}$$ is the drag force, which is by definition the force component in the direction of the flow velocity See more General In general, $${\displaystyle c_{\mathrm {d} }}$$ is not an absolute constant for a given body shape.
