Communicating Vessels

Communicating Vessels

 

vessels that are interconnected at the bottom (see Figure 1). When communicating vessels with diameters large enough to negate the capillary effect are filled with the same fluid, the fluid levels are of the same height regardless of the shape of the vessels. This is the working principle of fluid manometers and water-gauges for steam boilers. If the communicating vessels are filled with different fluids, the heights of the fluid columns (measured from the surface where the fluids

are in contact with each other) are inversely proportional to the densities; that is, ρ1h1 = ρ2h2, where ρ1, ρ2, h1, and h2 are, respectively, the densities and heights of the fluid columns. This relation is used to determine the density of a fluid. If, however, one of the legs of the communicating vessels is sealed, then the level difference will depend on the pressure in the sealed leg; this is the working principle of sealed manometers.

It is because of the lack of real growth in the economy that these are all communicating vessels, a symbiotic relationship with fees and taxes paid into the economy, without any fundamental creation of wealth, in essence, creative accounting.
Even without the European designation of Western Balkans for the countries of the region, who are strongly committed to joining the EU, political connoisseurs know perfectly well that the political developments in one country invariably have an effect on the political situation in all the other countries of the region as if they were communicating vessels. The Albanian question, that is, the idea of uniting all Albanians in the region coming to the spotlight again usually has this effect.
The current agency model is dysfunctional because, no matter how much clients insist on and push for integration, ask us to play nice and get us to work together, and no matter how hard we proclaim that we accept it and approach it in good faith, this model remains disaggregated and, therefore, cannot function like communicating vessels of information, data, knowledge and insight.
