# How to Calculate and Solve for Drag Force for Moving Particle | Mineral Processing

**Last Updated on May 17, 2024**

The image above represents drag force for moving particle. To calculate drag force for moving particle, three essential parameters are needed and these parameters are **Mass of Solid (m _{s}), Mass of Fluid (m_{f})** and

**Acceleration due to Gravity (g).**

**The formula for calculating drag force for moving particle:**

D = (m_{s} – m_{f})g

Where:

D = Drag Force for Moving Particles

ms = Mass of Solid

mf = Mass of Fluid

g = Acceleration due to Gravity

Let’s solve an example;

Find the drag force for moving particles when the mass of solid is 14, the mass of fluid is 12 and the acceleration due to gravity is 10.

This implies that;

ms = Mass of Solid = 14

mf = Mass of Fluid = 12

g = Acceleration due to Gravity = 10

D = (m_{s} – m_{f})g

That is, D = (14 – 12)10

D = (2)10

D = 20

Therefore, the **drag force for moving particles **is **20 N.**

**Calculating the Mass of Solid when the Drag Force for Moving Particles, the Mass of Fluid and the Acceleration due to Gravity are Given**

m_{s} = (^{D} / _{g}) + m_{f}

Where:

ms = Mass of Solid

D = Drag Force for Moving Particles

mf = Mass of Fluid

g = Acceleration due to Gravity

Let’s solve an example;

Find the mass of solid when the drag force for moving particles is 10, the mass of fluid is 4 and the acceleration due to gravity is 5.

This implies that;

D = Drag Force for Moving Particles = 10

mf = Mass of Fluid = 4

g = Acceleration due to Gravity = 5

m_{s} = (^{D} / _{g}) + m_{f}

That is, m_{s} = (^{10} / _{5}) + 4

m_{s} = 2 + 4

m_{s} = 6

Therefore, the **mass of solid **is **6.**

**Calculating the Mass of Fluid when the Drag Force for Moving Particles, the Mass of Solid and the Acceleration due to Gravity are Given**

m_{f} = m_{s} – (^{D} / _{g})

Where:

mf = Mass of Fluid

D = Drag Force for Moving Particles

ms = Mass of Solid

g = Acceleration due to Gravity

Let’s solve an example;

Find the mass of fluid when the drag force for moving particles is 24, the mass of solid is 12 and the acceleration due to gravity is 6.

This implies that;

D = Drag Force for Moving Particles = 24

ms = Mass of Solid = 12

g = Acceleration due to Gravity = 6

m_{f} = m_{s} – (^{D} / _{g})

That is, m_{f} = 12 – (^{24} / _{6})

m_{f} = 12 – 4

m_{f} = 8

Therefore, the **mass of fluid **is **8.**

**Calculating the Acceleration due to Gravity when the Drag Force for Moving Particles, the Mass of Fluid and the Mass of Solid are Given**

g = ^{D} / _{(ms – mf)}

Where:

g = Acceleration due to Gravity

D = Drag Force for Moving Particles

ms = Mass of Solid

mf = Mass of Fluid

Let’s solve an example;

Find the acceleration due to gravity when the drag force for moving particles is 40, the mass of solid is `15 and the mass of fluid is 5.

This implies that;

D = Drag Force for Moving Particles = 40

ms = Mass of Solid = 15

mf = Mass of Fluid = 5

g = ^{D} / _{(ms – mf)}

So, g = ^{40} / _{(15 – 5)}

g = ^{40} / _{10}

g = 4

Therefore, the **acceleration due to gravity **is **4.**
