English: Method:
It connects to a compressor to a transparent tube that has a central constriction (venturi). A U-tube manometer measures the pressure difference between a point where the section is narrower and a point where it is wider. The air flows in from one end of the tube and then the other and manometer is observed. Remarks: When the air flows through the tube, there is a lower pressure in narrower tube section and this value is independent from the end from which the air is introduced. In the area where the pipe diameter is smaller, the air flow in fact has greater speed, which results in a lower pressure in accordance with Bernoulli's equation. |
