Answer: b) 30
Explanation:
To find the length-to-diameter ratio, we can simply divide the height of the tube by the diameter of the tube.
Since the height is 1.5 m and the diameter is 0.05 m:
Length-to-diameter ratio = [tex]\dfrac{1.5}{0.05}[/tex]
Length-to-diameter ratio = 30
The length-to-diameter ratio of the standard vertical short tube evaporator is b) 30.
