During an incompressible flow density changes

WebWhen fluid is flowing and it's density does't change during the flow even fluid is compressible in nature, then flow is called incompressible. It's is a flow property, it's … WebCompressible flow differs from incompressible flow in at least the following respects: 1. The density of the flow becomes a variable. 2. The flow speeds are high enough that the flow kinetic energy becomes important and therefore energy changes in the flow must be considered. This couples the science of thermodynamics into the aerodynamic ...
