• To analyze temperature changes

How does the bubble fraction change with height above the gas distributor?

• It remains nearly constant

• It decreases linearly

• It fluctuates randomly

• It increases exponentially

What was the relationship between bubble size and superficial gas velocity?

• Bubble size decreases with increasing velocity

• Bubble size is independent of gas velocity

• Bubble size remains constant regardless of velocity

• Bubble size increases with increasing velocity

What is the main conclusion regarding the bubble velocity?
