Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. If the fluid is a liquid, c d {\displaystyle c_{\rm {d}}} depends on the Reynolds number ; if the fluid is a gas, c d {\displaystyle c_{\rm {d}}} depends on both the Reynolds number and the Mach number .
Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...
Iron supplements, also known as iron salts and iron pills, are a number of iron formulations used to treat and prevent iron deficiency including iron deficiency anemia. [ 11 ] [ 12 ] For prevention they are only recommended in those with poor absorption , heavy menstrual periods , pregnancy , hemodialysis , or a diet low in iron.
Iron preparation is the formulation for iron supplements indicated in prophylaxis and treatment of iron-deficiency anemia. Examples of iron preparation include ferrous sulfate, ferrous gluconate, and ferrous fumarate. It can be administered orally, and by intravenous injection, or intramuscular injection. [1] Early Iron Supplement for Anemia
Ghyssaert says that those with chronic infections, such as hepatitis C, HIV, malaria, ulcerative colitis, or Crohn’s disease, shouldn’t take iron supplements unless directed to do so by their ...
For an object with well-defined fixed separation points, like a circular disk with its plane normal to the flow direction, the drag coefficient is constant for Re > 3,500. [17] The further the drag coefficient C d is, in general, a function of the orientation of the flow with respect to the object (apart from symmetrical objects like a sphere).
