3
The approximate height of a blast furnace having a useful volume of 2000 m3 is about __________ metres
Discuss
Answer & Solution
Answer: Option C
Solution:
In chemical engineering, the approximate height of a blast furnace can be estimated based on its useful volume.

A commonly used estimation is that the height of a blast furnace is approximately 10 to 30 times its useful volume.

Given that the useful volume of the blast furnace is 2000 m3, we can estimate the height as follows:

Height ≈ 10 to 30 * Volume

Taking the average value (20 times the volume) for estimation:
Height ≈ 20 * 2000 m3
Height ≈ 40000 m3


Therefore, the approximate height of the blast furnace is 55 metres, which is closest to Option C.
