ABSTRACT: The main objective of this paper is to form source equation for cavitation.Mathematical analysis of physical phenomenon gives an ease for the study of parameters. Cavitation phenomenon critically affects several applications of hydronautics and hydrodynamics. cavitation shows losses in several turbines as well as pumps. Inception of cavitation over a surface caused due to fall in pressure below atmospheric. Pressure difference in flow gives rise to spherical bubbles. For physical interpretation one can think for coefficient of pressure as threshold value for inception of cavitation. Deciding parameters for range of operation of rotodynamic machines and performance of same can be decided with mathematical equation. Simulation of Mathematical equation on computer will give cost efficient experimental base for designing machines
