A sparged stirred-tank reactor holds 800 L of culture…
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
A sparged stirred-tank reactor holds L of culture. It is given L of sterile air for each litre of culture in each minute.
- What is the air flow in litres in each minute?
- How many cubic metres of air does the reactor use in one hour?
Need a reminder? The key ideaShow
A stirred-tank reactor mixes with a stirrer. A sparged stirred-tank reactor also bubbles sterile air. The parts are the agitator, the oxygen delivery, the foam control, the temperature control, the pH control and the sampling ports. Air flow volume air rate. Product of a batch volume product in each litre.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. L; L of air for each litre in each minute.
Plan. Air flow volume air rate.
Step 1. (a) L/min.
Step 2. (b) In an hour: L. L is m, so the air is m.
Answer: L/min; m.
Check. Double the volume and the air flow doubles too, so the air flow per litre does not change.
