Closed pipe (bottle) fundamental f = v/4L.

About Closed Pipe Calculator

The Closed Pipe Calculator solves f₁ = v / (4L) for you with the full working shown — every substitution, every unit, every step, exactly the way a good teacher writes it on the board. Blow across a bottle with 20 cm of air: ~429 Hz.

Frequently asked questions

What formula does the Closed Pipe Calculator use?+

It uses f₁ = v / (4L). The steps section shows the formula with your actual numbers substituted, so you can follow (and verify) every stage of the calculation rather than trusting a black box.

What should I keep in mind when using this calculator?+

Blow across a bottle with 20 cm of air: ~429 Hz. Closing one end buys an octave of depth for the same length (v/4L vs v/2L) but forfeits the even harmonics — the hollow, woody character of a clarinet or stopped organ pipe.

Is the Closed Pipe Calculator free to use?+

Completely free, with no sign-up or limits. All computation happens client-side in your browser, so it is fast, private, and works even on slow connections once the page has loaded.

Can I use this for homework, teaching or exam prep?+

That is exactly what it is built for. The step-by-step working mirrors how solutions are presented in class, so you can check homework, build worked examples for teaching, or practise method recall before exams.
