Rise Velocity of Bubble Calculator

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Rise Velocity of Bubble - (Measured in Meter per Second) - Rise Velocity of Bubble is the Velocity of Bubble when Rising, at Mininmum Fluidizing Conditions.
Diameter of Bubble - (Measured in Meter) - Diameter of Bubble is the Bubble Diameter passing through Fluid.

STEP 1: Convert Input(s) to Base Unit

Diameter of Bubble: 0.048 Meter --> 0.048 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

u_br = 0.711*sqrt([g]*d_b) --> 0.711*sqrt([g]*0.048)

Evaluating ... ...

u_br = 0.487809840719926

STEP 3: Convert Result to Output's Unit

0.487809840719926 Meter per Second --> No Conversion Required

FINAL ANSWER

0.487809840719926 ≈ 0.48781 Meter per Second <-- Rise Velocity of Bubble

What is Bubbling Fluidized Bed ?

A Bubbling Fluidized Bed(BFB) is a type of fluidized bed reactor or system characterized by the bubbling or churning motion of the solid particles within the bed. In a fluidized bed, a gas (usually air or another gas) is passed through a granular material at a sufficient velocity to suspend the particles and create a fluid-like behavior.

What are Fluidized Reactors ?

Fluidized bed reactors are a type of chemical reactor where a bed of solid particles is suspended and behaves like a fluid due to the upward flow of gas.
