Here is how the Rise Velocity of Bubble in Bubbling Bed equation looks like.

2.609 = 4.08 - 1.941 + 0.47

2.609m/s = 4.08m/s - 1.941m/s + 0.47m/s

2.609 = 4.08 - 1.941 + 0.47

Rise Velocity of Bubble in Bubbling Bed Solution

Follow our step by step solution on how to calculate Rise Velocity of Bubble in Bubbling Bed?

FIRST Step Consider the formula

u b = u i - u mf + u br

Next Step Substitute values of Variables

∴

u b = 4.08m/s - 1.941m/s + 0.47m/s

Next Step Prepare to Evaluate

∴

u b = 4.08 - 1.941 + 0.47

LAST Step Evaluate

∴

u b = 2.609m/s
