The Graetz number is concerned with the___________________
Correct answer: D. Heat transfer in laminar flow
- A. Mass transfer between a gas and a liquid
- B. Absorption with chemical reaction
- C. Heat transfer in turbulent flow
- D. Heat transfer in laminar flow
Explanation
The Graetz number characterizes developing heat or mass transfer in internal flow, and in this context it is especially associated with heat transfer in laminar flow. Turbulent heat transfer is more commonly correlated with Reynolds, Prandtl and Nusselt numbers.
