Drag force for a body moving in a fluid of certain density Solution

STEP 0: Pre-Calculation Summary
Formula Used
Drag Force = Coefficient of drag*Area of Surface*Density*(Velocity^2)/2
FD = CD*A*ρ*(v^2)/2
This formula uses 4 Variables
Variables Used
Coefficient of drag- The Coefficient of drag 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.
Area of Surface - The Area of Surface is the surface of the object where the drag force takes place due to the boundary layer. (Measured in Square Meter)
Density - The density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object. (Measured in Kilogram per Meter³)
Velocity - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time. (Measured in Meter per Second)
STEP 1: Convert Input(s) to Base Unit
Coefficient of drag: 0.01 --> No Conversion Required
Area of Surface: 10 Square Meter --> 10 Square Meter No Conversion Required

What is drag force?

A drag force is the resistance force caused by the motion of a body through a fluid, such as water or air. A drag force acts opposite to the direction of the oncoming flow velocity.

What is drag coefficient?

In fluid dynamics, the 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. It is used in the drag equation in which a lower drag coefficient indicates the object will have a less aerodynamic or hydrodynamic drag.
