The Prandtl number is the
The Prandtl number is the
Show Hint
Prandtl = momentum diffusivity / thermal diffusivity
Updated On: May 21, 2025
- Ratio of kinematic viscosity to thermal diffusivity
- Ratio of thermal diffusivity to kinematic viscosity
- Product of thermal diffusivity and kinematic viscosity
- Ratio of absolute viscosity to thermal conductivity
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Prandtl number ($Pr$) is defined as the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity: \( Pr = \frac{\nu}{\alpha} \).
