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)
