Abstract

Part I: An apparatus has been constructed for the determination of the thermal conductivity of fluids. In this equipment the thermal flux between concentric spheres is measured. The apparatus has been used to measure the thermal conductivity of nitrogen dioxide in the liquid state at 40°, 100°, and 160°F., and at pressures up to 5000 pounds per square inch.

Part II: The thermal conductivity of nitric oxide was measured at atmospheric pressure from 40° to 400°F., and the variation of its thermal conductivity with pressure was observed at 40°, 220°, and 340°F. to a maximum pressure of 1400 pounds per square inch. At higher pressures the nitric oxide was found to undergo catalytic decomposition.

Part III: A rolling ball viscometer was utilized to measure the viscosity of nitrogen dioxide and mixtures of nitrogen dioxide and nitric oxide. A temperature range of 400 to 280°F. was used at pressures from bubble point to 5000 pounds per square inch. Mixtures containing up to 20 weight per cent nitric oxide were studied.
