1.	What is the unit of turbulent Schmidt/Prandtl number?(a) m^2/s(b) It is dimensionless(c) m^2/s^2(d) m/s^2I had been asked this question in unit test.This question is from Turbulent Schmidt Number topic in division Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct option is (b) It is dimensionless Explanation: Both viscosity and diffusivity are in the same UNITS. As the turbulent Schmidt or PRANDTL NUMBER is the ratio of viscosity to CONDUCTIVITY, the number BECOMES dimensionless. So, it does not have units.
