= 9A.5. Estimation of the thermal conductivity of a pure liquid. Predict the thermal conductivity of liquid HO at 40C and 40 megabars pressure (1 megabar 106 dyn/cm). The isothermal compressibility, (1/p)(ap/ap)T, is 38 x 10-6 megabar and the density is 0.9938 g/cm. Assume that C = Cy. Answer: 0.375 Btu/hr.ft. F

9A.5. Estimation of the thermal conductivity of a pure liquid. Predict the thermal conductivity of liquid H2O at 40C and 40 megabars pressure (1 megabar =106 dyn /cm2). The isothermal compressibility, (1/)(/p)T, is 38106 megabar 1 and the density is 0.9938g/cm3. Assume that C~p=C~V. Answer: 0.375Btu/hrftF
