The paper is smoothed and pressed to remove trapped air.
soundproof cork insulation;a layer of trapped air that serves as insulation.
Bleed test cocks No.2,3 and4 to remove any trapped air.
While there is still sufficient trapped air within the container to keep it buoyant, it will float.
Open bleed port at high point in system and vent trapped air until a solid stream of liquid emerges.
This pressure closes the reed valve so that further downward movement of the piston compresses the trapped air-fuel mixture in the crankcase.
The trapped air in the diaphragm will force the diaphragm between the inside of the sleeve and the outside of the piston.
The mathematical analysis shows that, with disregarding local head losses and by means of different simplified rigid models, the calculated results of the maximum pressure in a pressurized pipe system containing trapped air mass are equal to and independent of the initial length of the water-column.
