Introduction:
Transport phenomena, the study of the transfer of mass, momentum, and energy in physical systems, is a fascinating field that plays a pivotal role in engineering processes. Whether you’re gearing up for an interview or simply seeking to deepen your understanding, tackling key questions related to transport phenomena is essential. In this article, we’ll explore 20 interview questions that cover fundamental concepts and principles within this dynamic field.
Here are 20 potential interview questions that might be asked in relation to transport phenomena:
What is transport phenomena, and why is it important in engineering processes?
Explain the differences between diffusion and convection.
How does Fick’s law describe molecular diffusion?
Discuss the significance of the Reynolds number in fluid mechanics.
Explain the concept of heat conduction and Fourier’s Law of Heat Conduction.
What are the major differences between laminar and turbulent flow?
How is convective heat transfer different from conductive heat transfer?
Describe the role of boundary layers in fluid flow.
Explain the Nusselt number and its importance in convective heat transfer.
What is the Stanton number, and how is it related to the Nusselt number?
Discuss the importance of Schmidt number in mass transfer.
Explain the analogy between heat and mass transfer.
How do you determine the effectiveness of a heat exchanger?
What is the role of Prandtl number in heat transfer?
Discuss the governing equations for fluid flow, heat transfer, and mass transfer.
