How do whistling tea kettles work

Anurag Agarwal delved deeper, examining how the two holes on a standard kettle whistle cap specifically interfere with the steam. Steam produced by the kettle first meets a hole in the kettle's spout, which is significantly narrower than the spout itself. As steam is forced through the narrow opening, it creates a "naturally unstable" jet, according to a written statement released by the university, "like the jet of water from a garden hose that starts to break into droplets after it has travelled a certain distance.

When the now-imperfect jet of steam reaches the second opening, it "cannot escape perfectly This pulse causes the steam to form vortices as it exits the whistle.

These vortices produce sound waves, creating the comforting noise that heralds a forthcoming cup of tea. Despite Strutt's theories about the kettle whistle, he concluded that "much remains obscure" about the sound.

The new findings have applications beyond tea kettles, as well. Kaitlyn Foley We all know the distinctive whistle of the tea kettle—but what actually produces that sound? In a paper published in the journal Physics of Fluids , researchers explained : The whistle in a steam kettle provides a near-perfect example of a hole tone system, in which two orifice plates are held a short distance apart in a cylindrical duct.

Now that they know what makes the whistle they can stop it in other situations: Using the knowledge gained from the study, researchers could potentially isolate and stop similar, but far more irritating whistles — such as the noise made when air gets into household plumbing, or damaged car exhausts.

In most cases, you should heat the water to a full boil when preparing black tea or herbal tea. Some teas, including green tea, white tea, and oolong tea, should be preparing with water that is steaming but not boiling. Pour the hot water over the tea leaves in your pot or cup, then let the leaves infuse for the desired amount of time. Empty any leftover water in your kettle, then place it back on its base to rest until the next time you need to make a cup of tea.

How to Use an Electric Tea Kettle Using an electric kettle is very similar to using a stovetop kettle, expect that you heat the kettle up using an electric base rather than on a stovetop.
