51500 Boyle's Law
Apparatus
U' tube, mounted on a wooden stand approximately 840 mm high.
The closed limb of 'J' tube is approximately 780 mm long x 8 mm
bore. A scale is fitted to the stand graduated from 0 at the
lower end to 80 cm at the top with millimeters in the centre and
figured every cm up either side. A loose fitting glass plunger
is pushed into the open limb of the 'J' tube and by
displacement, the height of the mercury can be adjusted from
about - 50 mm to + 450 mm relative to the closed end. |

51501 Boyle's Law
Apparatus
Comprising two glass tubes, both approximately 220 mm long x 8
mm inside diameter, one closed at the top and the other tube
open. their lower ends are connected together by 1 meter of
rubber pressure tubing. Both tubes are mounted on sliding
brackets which may be locked in any position on the metal
supporting rods. the stand is of polished wood, and carries a
scale graduated from 0 to 100 cm with millimeter divisions in
the centre and figured every cm either side. Supplied without
Mercury. |

51502 Bourdon Gauge
For the measurement of actual ( absolute ) gaseous pressure.
This apparatus is a laboratory demonstration version of the
standard Bourdon type of pressure gauge widely used in industry.
The instrument comprises a circular gauge having an overall
diameter of 100 mm. The dial read 0 to 100 Ib/in2 and 0 to 7
kg/cm2. The gauge is carried upon a circular pillar 19 x 16 mm
diameter. A tubing 8 mm diameter projects from the side of the
pillar to provide connection with the system under
investigation. The complete apparatus is provided with a heavy
cast iron base. |
