c) If the engine is connected at the intermediate point, a part from the energy will be absorbed by the engine, or stationary wave will persist with reduced amplitude between the generator (g) and engine, the liquid state between it could be considered as result of two overlapped waves: one stationary wave and one progressive wave.
If all taps are closed, in the pipe will appear stationary waves, having the maximum of variation of pressure at the end of (r) and at [lambda]/2--(though in b point).
We will have then overlapped in the pipes a system of stationary waves and a system of mobile waves along the pipe, though there will not be any point in the pipe where the variation of the pressure will be permanently zero.
The quantitative measures got the name of stationary wave ratios (RUS), and defined by relation [Darabont, 1983]:
Where: RUS--is stationary wave coefficient; Pmax--maxim sonic pressure; Pmin--minim sonic pressure; A--amplitude of incident wave; B--amplitude of reflected wave.
4 has depicted the block diagram for phonic-absorbent measurement by stationary waves with Kundt tub.
He has since gone on to surf more than 200 stationary waves in rivers around the world.
