Estimation of the thermal conductivity of a dense gas, predict the thermal conductivity of methane at 110.4atm and 127°F by the following methods: 

(a) Use Fig. 9.2-1. Obtain the necessary critical properties from Appendix E. 

(b) Use the Eucken formula to get the thermal conductivity at 127°F and low pressure. Then apply a pressure correction by using Fig. 9.2-1. The experimental value 2 is 0.0282 Btu/hr. ft. F
