Space time in flow reactor is____________________?
Correct answer: D. Both A. and B.
- A. Usually equal to the residence time
- B. The reciprocal of the space velocity
- C. A measure of its capacity
- D. Both A. and B.
Explanation
Space time is reactor volume divided by inlet volumetric flow rate, and it is the reciprocal of space velocity. For ideal flow under usual steady conditions, it is also commonly equated with residence time.
