Pressure Gauge
The apparatus has two pressure gauges each
of which shows the GAUGE pressure in kPa. For use with the thermodynamic charts,
these gauge readings will have to be converted to ABSOLUTE pressure. One
atmosphere corresponds to 1.01325 x 105 Pa.
These
gauges are mechanical and use the deformation of a curved, sealed, hollow
tube to indicate its internal pressure. Such a gauge is called a Bourdon
tube gauge. |
