measure pressure by boring two operation holes on both sides of a construction place of the gas transport tube, connecting a pressure gauge to one operation hole and putting a bag body for sealing closely to the construction place from the other, and observing variation on the pressure gauge. ...
WATER COLUMN TUBE FOR MEASURING CENTRAL VEIN PRESS 优质文献 相似文献PRESSURE-CONTROL UNIT FOR USE WITH THE PRESSURE-PLATE APPARATUS FOR MEASURING MOISTURE SORPTION AND TRANSMISSION BY SOILS A table of parts and dimensions is given with. a diagram of the apparatus and a detailed description of its...
Each column section of different geometry or load is loaded with a set of trays (12) with air water system consisting at least of two trays having identical geometry (13,13a) and one air distributor (14). On the basis of the recognition that each set of trays (12) may be regarded as...
The gas absorption/chemical reaction (GACR) method developed in chemical engineering to measure gas–fluid interface in reactor systems is adapted for natural porous geologic media. Several series of column experiments were conducted using model glass beads and a natural sand to determine optimal operat...
A method for continuously measuring the production of liquid from a liquid-gas mixture wherein the liquid produced is separated by projecting it along the cylindrical surface (9) of a meter receiver, while the gas is sucked up out of the mixture through a tube-like float (8) which fluctuate...
The insulating oil is circulated through an upper, a lower parts of the gas extraction chamber 23a by three-way valves 25a, 25b. A gas extracted from the insulating oil is injected to a pressure-reduced space in the gas extraction chamber 23a which is formed when a bellows 23b moves down...
Thus, the height to which the mercury rose in the glass tube represented normal air pressure (that is, 1 atm.) Torricelli discovered that at standard atmospheric pressure, the column of mercury rose to 760 millimeters. The value of 1 atm was thus established as equal to the pressure ...
