Answer:
Explanation:
What is flow rate?
Flow rate is the volume of fluid per unit time flowing past a point through the area
the formula is Q=Av
where A= area
v= flow velocity
step one:
given data
radius r1= 3cm= 0.03m
radius r2=2cm= 0.02m
velocity v1=?
velocity v2=5m/s
The area A1
[tex]Area= \pi r^2\\\\Area- A1= 3.142*0.03^2\\\\A1= 0.0028m^2[/tex]
The area A2
[tex]Area= \pi r^2\\\\Area- A2= 3.142*0.02^2\\\\A1= 0.0013m^2[/tex]
Step two:
For the continuous flow
Q1=Q2
A1v1=A2v2
0.0028*v1=0.0013*5
v1=0.0065/0.0028
v1=2.32m/s
The bloods velocity in the 3 cm radius unconstricted region is 2.32m/s
