HEAT CAPACITY DETERMINATION OF MINERAL AND SYNTHETIC ENGINE OILS, LUBRICANTS, FUELS, AND HYDRAULIC FLUIDS IN THE TEMPERATURE RANGE 70°-500℉

摘要

The heat capacities of 33 mineral and synthetic engine oils, lubricants, fuels, and hydraulic fluids were measured over a temperature range of 80° to 500°F.nCalorimeter constants were obtained by internal standardization foregoing the use of a standard liquid.nThe calculated errors in the final results were 3 to 5 per cent.nA comparison of latent heats of vaporization of phenyl ether samples is included.
