The space time is equivalent to the holding time in a steady state mixed reactor for_____________________?
Correct answer: C. Constant fluid density systems
- A. Non-isothermal gas reaction
- B. Variable fluid density systems
- C. Constant fluid density systems
- D. Gas reactions with changing number of moles
Explanation
Space time is V divided by the inlet volumetric flow rate, whereas holding time uses the actual flow rate inside the reactor. These are equal when fluid density and volumetric flow remain constant.
