Find the dimensions of $C_{fx}$ in the relationship: $C_{fx}=2.(St).(Pr{)}^{\frac{2}{3}}$ where $St=\frac{h}{u{C}_p}$ is the Stanton number and $Pr=\frac{C_p}{}$ is the Prandtl number.

Definitions:

$h$ : heat transfer coefficient $(\frac{W}{m^2}(K))$

$C_p$ : heat capacity $(\frac{J}{k}gK)$

$$ : density $(k\frac{g}{m^3})$

$C_p$ : heat capacity $(\frac{J}{k}gK)$

$$ : viscosity $(Pa.s)$

$u$ : velocity $(\frac{m}{s})$

$$ : thermal conductivity $(\frac{W}{m}K)$
