Publisher's Synopsis
Excerpt from Emissivity of Heat From Various Surfaces, With Special Reference to Warm-Air Furnace Installations: Results of Comparative Tests on Covered and Uncovered Sheet Metal Surfaces Made in Connection With the Warm-Air Furnace Investigation
The report mentioned in paragraph 2, which was made at Colum bus, Ohio, gave the results of tests on the Auxiliary Testing Plant (see Fig. It was difficult to obtain entirely satisfactory data on this plant because of the variation in the velocity of the air flowing up the leader and the difficulty of correctly measuring the temperature of the air, as described later in this bulletin. It was therefore decided that a special apparatus should be devised which would eliminate possible errors in temperature measurements.
