Question

Thermal diffusivity is given by

Options:

A . `(k)/(rho.C_p)`

B . `(rho.C_p)/(k)`

C . `(C_p mu)/(a)`

D . `(mu)/(h.C_p)`

Answer: Option A

Thermal diffusivity =`(k)/(rho C_p)`

k is thermal conductivity (W/(mK).

`rho` is density (kg/m³).

_{`C_p`} is specific heat capacity (J/(kgK)).
