Its the Speed of which the flow travels, Water will travel faster than blood or yogurt
Viscous fluid flow occurs when a fluid's viscosity causes resistance to flow, leading to the formation of layers within the fluid. Non-viscous fluid flow, on the other hand, involves a fluid that flows without resistance or layering, typically with low viscosity.
By viscous, I think you mean viscosity. Viscous is a adjective referring to the thickness of a substance; therefore, yes, ketchup is somewhat viscous.
Viscosity denotes opposition to flow.
It is the ability of the liquid to flow. The higher the viscosity, the less the ability to flow. For example, oil is more viscous than water; honey is more viscous than oil.
Viscous fluids are difficult to pour or flow easily because they have high resistance to deformation and flow. This resistance is due to the strong intermolecular forces present in viscous fluids, which make it harder for the molecules to move past each other. As a result, viscous fluids flow slowly and require more force to pour compared to less viscous fluids.
Glass is not considered viscous at room temperature. It is a solid material that does not flow or deform over time like a viscous liquid would.
Higher viscous magma flows slower and with more difficulty compared to lower viscous magma. This is because higher viscous magma has a higher resistance to flow due to its thicker consistency, which can result in more explosive and violent eruptions.
Viscous flux usually refers to laminar flow. In most contexts, it refers to something like creeping flow or Poiseuille flow. Viscous flus usually arises from an external body force acting on a fluid. The external body force is usually pressure, or in some instances, centripetal force or magnetism.

Warming a viscous fluid generally decreases its viscosity, making it less resistant to flow. This decrease in viscosity typically results in an increase in flow rate for the fluid.
Blood is viscous, as it contains a hugely populous density of red blood cells therefore making it viscous. A comparison would be to water, which is less than 3 times as viscous as blood, as it contains around less than 3 times the amount of molecules than in blood.
Viscosity is the measure of a fluids resistance to flow. The higher the viscosity the more viscous (the more resistance it has to flow); honey is generally much more viscous than water.
