Specific Heat of Lubricating Oil
Specific Heat of Lubricating Oil
(OP)
writing a program for cooling of lubricating oil used in natural gas engines and compressors. Any web site showing the specific heat as a function of viscousity and temperature?
thanks
thanks





RE: Specific Heat of Lubricating Oil
the back of any heat transfer book has to have an appendix of fluid properties as functions of temperature.
but, that aside ...light oil at 150F , Cp = .48 BTU/lbm/F (per Kreith, Table A-3)

t,oC Cp, kJ/(kg.K)
0 1.796
20 1.880
40 1.964
60 2.047
80 2.131
100 2.219
120 2.307
140 2.395
160 2.483
It also provide viscosities and othe relevant thermophysical properties.
RE: Specific Heat of Lubricating Oil
where t is in deg C, and d is density of the oil at 20 deg C.
Common Cp values at 20 deg C:
Polyhydric alcohols, 2.43; petroleum oils, 1.88; silicones, 1.47.
