Describe the effect on the flow rate given each of the following changes. Each change is to the original system and all other variables are held constant:
The radius decreases
The pipe length decreases
The fluid viscosity decreases
The pressure difference decreases
Homework Answers
Flow rate is given by:
Q = Av
where A is the area and v is the velocity.
So, flow rate is dependent on area(and thus velocity) and velocity only.
Thus we have the following:
The radius decreases
Flow rate decreases.
The pipe length decreases
No change.
The fluid viscosity decreases
This increases velocity and thus flow rate increases.
The pressure difference decreases
This increases velocity and thus flow rate increases.

1) 25pt)Poiseuille’s Law is a fundamental law of fluid dynamics that describes the flow velocity of a viscous incompressible fluid in a cylinder. It says that in a cylinder of radius R and length L, the velocity of the fluid r (where r ≤ R) units from the center line of the cylinder is: ? = ? 4?? (? 2 − ? 2 ), where P is the difference in the pressure between the ends of the cylinder and ν...

Recall that the Reynolds number is a dimensionless number that we use to discuss the flow charecteristics of moving fluids. Generally speaking it is the ratio of momentum forces to viscous forces, and it depends on the diameter of the pipe, the density of the fluid, the velocity of the moving fluid, and the viscosity of the moving fluid. It is normally given by Re Where Re - Reynolds number [dimensionless) p- fuid density v- fud velocity D- pipe diameter...
