Can anyone give me a relationship for the turbulent drag force on an object with a cross sectional area A and a speed v in a medium with density p please?
Thanks
Thanks
Turbulent drag force is a type of drag force that occurs when an object moves through a fluid at high velocities, causing the fluid to become turbulent. This force is caused by the friction and resistance between the object and the fluid, and it can significantly affect the movement and speed of the object.
The turbulent drag force is directly proportional to the projected area (A) of the object, the velocity (v) at which it is moving, and the density (p) of the fluid it is moving through. This means that an increase in any of these variables will result in a corresponding increase in the turbulent drag force.
The magnitude of turbulent drag force is influenced by several factors, including the shape and size of the object, the velocity at which it is moving, the density and viscosity of the fluid, and the roughness of the object's surface.
Turbulent drag force differs from laminar drag force in that it occurs at higher velocities and is more chaotic. Laminar drag force, on the other hand, occurs at lower velocities and is more orderly. Turbulent drag force is also typically larger in magnitude compared to laminar drag force.
Turbulent drag force can be reduced by altering the shape or surface roughness of the object, reducing its velocity, or by using certain types of coatings or additives in the fluid to decrease its viscosity. Additionally, streamlining the object can also help reduce the effects of turbulent drag force.
