Defining viscosity and thermal conductivity as a function of fluid temperature

      Hello,
      I wrote some expressions to define viscosity and thermal conductivity as a function of fluid temperature and just want to see whether they are correct or not. (it should be mentioned there is a solid domain and so there is solid temperature too)


      Dynamic viscosity

      3.674e-07*((Temperature/1[K])^0.7) [Pa s]


      Thermal conductivity
      0.002953*((Temperature/1[K])^0.7) [W m^-1 K^-1]


      Many thanks in advance
