Falling Speed given Ratio of Removal with respect to Settling Velocity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Falling Speed = Removal Ratio e*Settling Velocity
v' = r*vs
This formula uses 3 Variables
Variables Used
Falling Speed - (Measured in Meter per Second) - Falling Speed is the speed of the particle having smaller diameter.
Removal Ratio e - Removal ratio e is the total amount of sludge removed from the sedimentation tank.
Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
STEP 1: Convert Input(s) to Base Unit
Removal Ratio e: 0.5 --> No Conversion Required
Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
v' = r*vs --> 0.5*1.5
Evaluating ... ...
v' = 0.75
STEP 3: Convert Result to Output's Unit
0.75 Meter per Second --> No Conversion Required
FINAL ANSWER
0.75 Meter per Second <-- Falling Speed
(Calculation completed in 00.004 seconds)

Falling Speed given Ratio of Removal with respect to Settling Velocity Formula

Falling Speed = Removal Ratio e*Settling Velocity
v' = r*vs

What is Removal Ratio ?

The removal ratio is defined as the ratio of the amount of sludge being discharged from the sedimentation tank in a given time period. Concentrated sludge leaving the bottom of the sedimentation tank, time for which the water is detained in the tank.

What is Sediment?

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

How to Calculate Falling Speed given Ratio of Removal with respect to Settling Velocity?

Falling Speed given Ratio of Removal with respect to Settling Velocity calculator uses Falling Speed = Removal Ratio e*Settling Velocity to calculate the Falling Speed, The Falling Speed given Ratio of Removal with respect to Settling Velocity formula is defined as when particle reach its terminal velocity, where gravitational force works downwards and buoyancy and viscous force work to dim particles falling. . Falling Speed is denoted by v' symbol.
