Pressure, buoyancy, Bernoulli, wave speed, Doppler and sound.
- Bernoulli Equation Calculator Solve Bernoulli’s equation for the downstream pressure or speed along a streamline.
- Buoyancy Calculator (Archimedes’ Principle) The buoyant force on a submerged object, whether it floats, and how much of it sits below the surface.
- Density Calculator (Mass ÷ Volume) Find density, mass or volume from the other two.
- Doppler Effect Calculator The frequency heard from a moving sound source, a moving listener, or both.
- Frequency and Period Calculator Convert frequency to period and back, with the angular frequency.
- Hydrostatic Pressure Calculator Pressure at a depth in a liquid, as gauge and absolute pressure.
- Mach Number Calculator Mach number from a speed and the air temperature, or a known speed of sound.
- Pressure Calculator (Force ÷ Area) Find pressure, force or area from the other two.
- Reynolds Number Calculator Reynolds number from density, speed, length and viscosity, with the likely flow regime in a pipe.
- Speed of Sound Calculator The speed of sound in air and other gases at any temperature.
- Standing Wave and Harmonics Calculator Resonant frequencies and wavelengths of a string or pipe, for any harmonic.
- Wave Speed, Frequency and Wavelength Calculator Find wave speed, frequency or wavelength from the other two, for sound, water or any other wave.
