As with the settling velocity of sediment grains in water it is dependent on the rust particle size, geometry, density etc.
But, as a generalisation the same equation to calculate the fall velocity of sediment in water appears to be multi-faceted, that is to say it has no parameters that implicitly restrict it to be used with water.
It is,
Fall velocity = Root of ((4/3*Cd) * ((ρs-ρ)/ρ)*g*D)
where the usual notation applies. It's pretty hard to follow typed out but im sure a quick Google search will provide you with this equation in an easier to read format!
Hope this helps/is right!

What suspends something?
A suspension is a heterogeneous mixture where solid particles are dispersed throughout a liquid or gas but are not dissolved. The solid particles remain suspended due to the constant motion of the particles in the liquid or gas, preventing them from settling. Examples include muddy water, powdered paint in water, and dust in the air.
What is the difference between HVAC diffuser's neck velocity and face velocity?
In HVAC terminology, a diffuser's neck velocity is defined as the velocity of air traveling through the duct work to the air outlet or inlet. The difference of the face velocity is this is a measurement of fume hood performance.
What causes variation in velocity of a particle?
Variation in velocity of a particle can be caused by changes in the magnitude or direction of the force acting on the particle, inertia of the particle, or interactions with other particles in the system. Additionally, external factors such as friction, air resistance, and gravitational forces can also influence the velocity of a particle.
How does air resistance affect terminal velocity?
Air resistance increases as an object's speed increases. At terminal velocity, the upward force of air resistance equals the downward force of gravity, resulting in a constant velocity. The greater the air resistance, the lower the terminal velocity of an object falling through the air.
How do you calculate velocity of air in a mine?
To calculate the velocity of air in a mine, you can use a device called an anemometer. An anemometer measures the flow and speed of air, providing you with the velocity information. Simply place the anemometer in the air flow in the mine and it will give you a reading of the velocity.
Is dust settling out of the air a chemical change?
No, dust settling out of the air is a physical change, not a chemical change. It is a result of gravity causing the dust particles to fall out of suspension in the air without any chemical reactions occurring.
Why do iron particles rust more in coastal areas?
Salty air, high ratio of moisture and relatively low temperature causes iron to rust quicker.
What is the settling of the particles on a sediment or other surface?
The settling of particles on a sediment or other surface is known as sedimentation. This process occurs when particles in a fluid, such as water or air, lose their kinetic energy and come to rest due to gravity or other forces. Over time, sedimentation can lead to the formation of layers of sediment on the surface.
What is the process of settling out and grading sediments called?
The process of settling out and grading sediments is called sedimentation. During sedimentation, particles in water or air settle down due to gravity, forming layers based on their size and density. These layers are then graded based on the size and composition of the sediment particles.
Rust chipping with air tools on ship?
When using air tools to remove rust on a ship, make sure to wear appropriate personal protective equipment such as goggles, gloves, and a mask to protect yourself from rust particles. Use a wire brush attachment on the air tool to effectively remove rust, and follow up with a rust inhibitor or primer to prevent future rusting. Regular maintenance and inspection of the ship's surfaces will help to identify and address rust early on.
What is the tendency for currents of air or water to separate sediments according to size called?
The tendency for currents of air or water to separate sediments according to size is called sorting. This process occurs when particles are transported by the flow of air or water, with larger particles settling out first followed by smaller particles, leading to the sorting of sediments based on their size.
What is the velocity of air in still air?
Speed of sound in still air is c ≈ 331 + 0.6 × T. T = Temperature. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Tendency for air currents of air or water to separate sediments according to size is called?
The tendency for air currents of air or water to separate sediments according to size is called sorting. Sorting occurs when sediments are transported and deposited, with larger and heavier particles settling out first followed by smaller and lighter particles. This process helps to form distinct layers of sediment with particles of similar sizes.
What air that gives rust to metals?
Explosure to moist air will form rust on metals.
