Effects of Seasonal Changes on the Velocity and Pressure of Standard Powders Stored in Leaky Containers. Effect of Storage of Standard Powders in Leaky Containers

摘要

Firings were made of standard powders which had been stored in leaky and tight containers. The velocities of the powders from leaky boxes were about 4 f/s lower than those of the tight boxes. Comparisons were obtained of the velocities of powders from leaky and tight boxes which had been fired in June and September. (Author)
