Biofluid dynamics is also an example of a biological fluid. Types of Fluids Fluids can be classified into four basic types. They are: An Ideal Fluid is a fluid that has no viscosity, means it will offer no resistance, pragmatically this type of fluid does not exist. It is incompressible in nature. Real fluids are compressible in nature. They offer some resistance and thus have viscosity. All Fluids existing are real fluids. A Newtonian Fluid is a fluid whose viscous shear stresses (acting between different layers of fluid and between the fluid layer and surface over which it is flowing) are directly
German resistance to Nazism Group Centre created what appeared to a viable structure for a new effort at organising a coup. Bock's dismissal did not weaken Tresckow's position. In fact he soon enticed Bock's successor, General Hans von Kluge, at least part-way to supporting the resistance cause. Tresckow even brought Goerdeler, leader of the civilian resistance, to Army Group Centre to meet Kluge – an extremely dangerous tactic. The entry of the Soviet Union into the war had certain consequences for the civilian resistance. During the period of the Nazi–Soviet Pact, the KPD's only objective inside Germany was to keep itself in existence: it
