Unpublished diagram, 'Figure 3' by G Robinson A small diagram showing the reservoir system described by Robinson in his third experiment into the absorbing power of steams. In the diagram, a jet escapes from an opening in the bottom of the reservoir, and is crossed transversely by one end of a small arched glass tube. The other end of the glass tube is dipped into a small reservoir of coloured liquid so that the flow from both reservoirs may be observed. Subject: Physics / Hydraulics / Fluid mechanics 1844
