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.
