Graetz number is given by__________________?
Correct answer: A. mCp/kL
- A. mCp/kL
- B. kL/mCp
- C. mCp/kμ
- D. kμ/mCp
Explanation
The Graetz number compares convective heat transport by the flowing stream with axial conduction, and is written as mCp/(kL), where m is the mass flow rate. Hence option a gives the standard form.
