Example 8.2-1 Effect of pressure on Thermal Conductivity

>  restart;
>  k0:=0.0159*Btu/(hr*ft*F); Given
>  Tc:=305.4*K; pc:=48.2*atm; From Appx B.1
>  T:=(153+460)/1.8*K;p:=191.9*atm; Given
>  Tr:=T/Tc;pr:=p/pc; Reduced temperature and pressure
>  krat:=4.7; From Fig. 8.8-2, this gives k/k0
>  k:=k0*krat;  The text found 0.075 Btu/(hr*ft*F), 
but the experimental value is reported as 
0.0453 Btu/(hr*ft*F)
