This calculator is used to calculate the size of a bubble of a known volume inside of a given tube. If the bubble is smaller than the inside diameter (ID) of the tube then the bubble is assumed to be spherical and a bubble diameter is calculated. If the diameter of a spherical bubble would be larger than the ID of the tube the the bubble is assumed to be cylindrical with a diameter equal to the the tube ID and the bubble length is calculated. Please note that this is an approximation and the actual shape of a bubble will be affected by other factors such as the surface tension of the liquid, liquid viscosity, orientation of the tube with respect to gravity, tube surface roughness, etc. In reality, most bubbles will have somewhat ellipsoidal ends.
