In fluid flow, and heat and mass transfer, one encounters (i) kinematic velocity (μ), (ii) molecular diffusivity (ζ) and thermal diffusivity (α). The units of these quantities are?
Aμ, α and θ all have units of m2/s
Bα and θ have units of m/s, while μ has unit of m2/s
Cμ, α and θ all have units of m/s
Dα and θ have units of m2/s, while μ has unit of m/s
Correct answer
D. α and θ have units of m2/s, while μ has unit of m/s
Explanation
The correct answer is α and θ have units of m2/s, while μ has unit of m/s.
