Another parts 's the results of pressure "spike" and therefore occurs within EVO, shown because of the peak in debt range inside the Figure A few, immediately after EVO. That tension increase, otherwise tension trend, moves on the tubing at amount of your neighborhood sonic acceleration and also the particle velocity of one's fuel flow. Whenever stress wave experience a change in cross-sectional an element of the tubing, an excellent mirrored stress revolution is generated, and that journey throughout the contrary recommendations. If for example the change in town is growing (one step, enthusiast, the atmosphere), the feeling of one's reflected tension revolution (compression otherwise extension) was upside-down.
