For the measurement of actual (total gaseous) pressure. Circular gauge, overall diameter 106mm, depth 40mm. The dial reads 0 to 3.4 x 105 Pa actual (total) pressure and the case has a clear perspex back so that the working parts may be seen. A tubule, 8mm diameter, provides connection to the system under investigation. The gauge is mounted on a heavy base 102 x 102 x 25mm, with rubber feet. Overall height: 220mm.
E8L20035 B. Bernoulli Tube
Glass tubing to demonstrate the Bernoulli effect produced by water-flow. Comprises a Bernoulli tube with central constriction, a constant-bore gradient tube, 6 lengths glass tubing, 2 swan- necked outlet tubes and 8 pre-cut lengths of connecting tubing. The 2 flow-tubes, each 500 x 13mm length 25mm x 150mm spacing, extended to form 500mm manometers with the lengths of glass tubing.
