A gas bubble (gas density 
; bubble diameter 
) is rising vertically through water (density 
; viscosity 
Pa.s). Force balance on the bubble leads to the following equation,
where 
is the velocity of the bubble at any given time 
. Assume that the volume of the rising bubble does not change. The value of 
.
The terminal rising velocity of the bubble (in 
), rounded to 2 decimal places, is 
cm/s.
