What is continuum hypothesis in fluid mechanics?
The continuum assumption is an idealization of continuum mechanics under which fluids can be treated as continuous, even though, on a microscopic scale, they are composed of molecules. Fluid properties can vary continuously from one volume element to another and are average values of the molecular properties.
Is Zfc consistent?
