Estimate the thermal conductivity of ethane at 1 bar and 450^{\circ} C.
Question 8.5: Estimate the thermal conductivity of ethane at 1 bar and 450...
Viscosity = 0.0134 mNs / m ^{2}
Specific heat capacity = 2.47 kJ / kg ^{\circ} C
k=0.0134\left(2.47+\frac{10.4}{30}\right)=0.038 W / m ^{\circ} C (8.13)
Experimental value, 0.043 W / m ^{\circ} C, error 12 per cent.
