Space time equals the mean residence time__________________?
Correct answer: D. When the density of the reaction mixture is constant
- A. For CSTR
- B. For large diameter tubular reactor
- C. For narrow diameter tubular reactor
- D. When the density of the reaction mixture is constant
Explanation
Space time is based on reactor volume divided by inlet volumetric flow, whereas mean residence time uses the actual flow within the reactor. They become equal when density, and therefore volumetric flow, remains constant.
