Experimental Study on the Power Sprayer. (2)

Condition in the Air Chamber of a Power Sprayer and Effect on It of Air Supply

Abstract

Air chambers which have various capacities and are made of transparent plastics were used. The investigation and observation were made concerning the changes of air and water in the air chambers caused by different working conditions.
The results obtained are as follows:
1) The relations between pressure and compression ratio were always constant, but the air-water ratios changed according to different quantities of absorption and loss of air even under the same pressure.
2) When the engine was operated continuously, the loss of air in the chamber became larger, depending upon how small the air chamber entrance was and how high the pressure. The change of pressure got somewhat larger as the amount of loss increased.
3) During the operation of the engine the amount of air 3 to 6 times as much as the capacity of the air chamber could be absorbed through the water absorbing tube. The larger the amount of absorbed air was, the smaller the change of pressure was.
4) The movement of the water on its surface was very small, and in the upper two-thirds of it the alternating current of water was hardly seen.
