The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Residence time is the time milk spends in the holding tube.
It is calculated from flow rate and tube dimensions.
Step 2: Key Formula or Approach:
Residence time = Volume of holding tube Volumetric flow rate.
Step 3: Detailed Explanation:
The average residence time is determined from:
- Volumetric flow rate of milk
- Dimensions (volume) of the holding tube
Other factors do not affect residence time.
Thus, the dimensions of the holding tube are used.
Step 4: Final Answer:
Residence time is determined from the dimensions of the holding tube.
Hence, the correct option is (C).
