Its general form is usually written aswhere See more Neglecting surface tension and viscosity, the equation was first derived by W. H. Besant in his 1859 book with the problem statement stated as An infinite mass of homogenous incompressible fluid acted upon by no forces is … See more More recently, analytical closed-form solutions were found for the Rayleigh–Plesset equation for both an empty and gas-filled bubble and were generalized to the N … See more The Rayleigh–Plesset equation can be derived entirely from first principles using the bubble radius as the dynamic parameter.
