Scheme occurrence of acoustic vibrations in the whistle when exposed to steam jet
The work of the subject can be demonstrated on the basis of simple experiment, the purpose of which is to monitor the state of water when increasing the temperature gradually:
- After installation of the kettle to the plate in the first stage there is liquid heating to a temperature of 20-50 ° C, resulting in the appearance of condensation droplets on the inner walls or the lid.
- The next step - raising the temperature to 80 ° C. If you look inside of the kettle, it can be seen that in the water produces a large amount of bubbles, begins oscillation of the fluid coming from the bottom, which undergoes the maximum heating.
- Achieving the desired temperature of 100 ° C, at which water boils to form steam. Since the space free of liquid within the kettle is very limited, the steam escapes through the jet nozzle, where there is a whistle, the sound emitting incrementally.
- Turning off the kettle, it can be seen that the whistle is lost because the vapor pressure decreases, which ceases to be formed with decreasing temperature.

Of course, each school physics know that the boiling point of water is 100 ° C. This is the limit when we manage to hear the work whistle.
When the temperature reached 100 ° C steam jet exits the nozzle, resulting in fluctuations plates, accompanied by sound
The source of the loud sound is a whistle that fits over the nose. It is most commonly made of metal (stainless steel), whose melting point is several times higher than that of boiling water. Inside whistle has two thin plates with symmetrically arranged with respect to each other holes. The gap between these plates is only a few millimeters.
With increasing temperature of the water in a small space inside space begins to accumulate pairs. The only way out for him is the tip. The jet of steam entering into the whistle is held under pressure between the plates, creating a swirl that interact with the main flow which escapes outwards. This leads to a whistling sound.
