The velocity, concentration and temperature boundary, for the boundary layer development on a flat plate during connective mass transfer will be same, if___________________?
Correct answer: A. NSc = NPr = NLe
- A. NSc = NPr = NLe
- B. NSc = 1
- C. NPr = NLe
- D. NSc = NLe
Explanation
The concentration and temperature profiles coincide with the velocity profile when the Schmidt, Prandtl and Lewis numbers satisfy NSc = NPr = NLe. This makes momentum, heat and mass diffusivities equivalent for boundary-layer development.
