What are fluids Grade 8?
A Fluid is a state of matter, such as liquid or gas, in which the component particles (generally molecules) can move past one another.
What is the relationship between flow rate and viscosity grade 8?
Flow rate is inversely proportional to viscosity.
What’s the relationship between viscosity and flow rate?
The short answer is; as viscosity increases, flow rates decrease.
What is viscosity in science?
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.

What is the unit of viscosity coefficient?
The coefficient of viscosity (η) is the ratio of applied stress to the rate of straining (change of strain with time). It is measured in units of poise; one poise equals one dyne-second per square centimetre.

| Increasing blood vessel length _______. | has the same effect as decreasing blood vessel radius and increases resistance to flow |
Does viscosity affect speed?
The faster the speed, the higher the viscosity. The density increases, the viscosity increases.
What is viscosity and its unit?
The definition of viscosity is as follows: Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre (N s m-2) or pascal-second (Pa s.) The dimensional formula of viscosity is [ML-1T-1].
What type of fluid is honey?
non-Newtonian fluid
Honey is an example of a non-Newtonian fluid – a fluid that changes its behavior when under stress or strain.
