This formula uses 5 Variables
Variables Used
Drag Coefficient - Drag Coefficient 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.
Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.
Frontal Area - (Measured in Square Meter) - Frontal Area of the body exposed to the flow, for a cylinder, is the product of diameter and length.
Density of Fluid - (Measured in Kilogram per Cubic Meter) - Density of Fluid is defined as the mass of fluid per unit volume of the said fluid.
Free Stream Velocity - (Measured in Meter per Second) - Free Stream Velocity is defined as at some distance above the boundary the velocity reaches a constant value that is free stream velocity.
STEP 1: Convert Input(s) to Base Unit
Drag Force: 80 Newton --> 80 Newton No Conversion Required
Frontal Area: 2.67 Square Meter --> 2.67 Square Meter No Conversion Required
Density of Fluid: 1.225 Kilogram per Cubic Meter --> 1.225 Kilogram per Cubic Meter No Conversion Required
Free Stream Velocity: 11 Meter per Second --> 11 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CD = (2*FD)/(A*ρFluid*(u^2)) --> (2*80)/(2.67*1.225*(11^2))
Evaluating ... ...
CD = 0.404284659355431
STEP 3: Convert Result to Output's Unit
0.404284659355431 --> No Conversion Required
FINAL ANSWER
0.404284659355431 0.404285 <-- Drag Coefficient

What is Convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced. It involves a bulk transfer of portions of the fluid.

What are the Types of Convection?

There are two types of convection, and they are: Natural convection: When convection takes place due to buoyant force as there is a difference in densities caused by the difference in temperatures it is known as natural convection. Examples of natural convection are oceanic winds. Forced convection: When external sources such as fans and pumps are used for creating induced convection, it is known as forced convection. Examples of forced convection are using water heaters or geysers for instant heating of water and using a fan on a hot summer day.

How to Calculate Drag Coefficient for Bluff Bodies?

Drag Coefficient for Bluff Bodies calculator uses Drag Coefficient = (2*Drag Force)/(Frontal Area*Density of Fluid*(Free Stream Velocity^2)) to calculate the Drag Coefficient, The Drag Coefficient for Bluff Bodies formula is defined as the function of Drag force, frontal area, density of fluid and free stream velocity. The force exerted on a solid body moving in relation to a fluid by the fluid's movement is known as a drag force. For instance, drag on a moving ship or drag on a flying jet. As a result, a drag force is a resistance created by a body moving through a fluid such as water or air. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag. It makes no difference whether the object moves through a static fluid or whether the fluid moves past a static solid object. Drag Coefficient is denoted by CD symbol.

How to calculate Drag Coefficient for Bluff Bodies using this online calculator? To use this online calculator for Drag Coefficient for Bluff Bodies, enter Drag Force (FD), Frontal Area (A), Density of Fluid Fluid) & Free Stream Velocity (u) and hit the calculate button. Here is how the Drag Coefficient for Bluff Bodies calculation can be explained with given input values -> 0.404285 = (2*80)/(2.67*1.225*(11^2)).
