WebIncompressible flow, in general terms of fluid mechanics, refers to a fluid that maintains constant density during a flow. To an extent, all fluid flows have some change in density when subjected to an external force or internal viscous forces; however, density variation is more prevalent in some analysis results than others. http://users.metu.edu.tr/csert/me305/ME%20305%20Part%206%20Differential%20Formulation%20of%20Fluid%20Flow.pdf
