Answer: the average velocity decreases
Explanation:
From the provided data we have:
Vessel avg. diameter[mm] number
Aorta 25.0 1
Arteries 4.0 159
Arteioles 0.06 1.4*10^7
Capillaries 0.012 2.9*10^9
from the information, let
be the mass flow rate,
is density, n number of vessels, and A is the cross-section area for each vessel
the flow rate is constant so it is equal for all vessels,
The average velocity is related to the flow rate by:

we clear the side where v is in:

area is π*R^2 where R is the average radius of the vessel (diameter/2)
we get:

you can directly see in the last equation that if we go from the aorta to the capillaries, the number of vessels is going to increase ( n will increase and R is going to decrease ) . From the table, R is significantly smaller in magnitude orders than n, therefore, it wont impact the results as much as n. On the other hand, n will change from 1 to 2.9 giga vessels which will dramatically reduce the average blood velocity
Tolerance is the acceptable amount of dimensional variation that still allows a part to perform as designed.
Any process will have variation and depending on the severity of the function some tolerance will be very small. For example the sheet metal thickness on portion of a space shuttle will have a much tighter tolerance than the thickness of a piece of lumber to build a house. Tighter tolerance of processes typically are related to more process control (e.g. money) thus designs should be fully vetted with process team before placing on a drawing.
Answer:n=0.973
Explanation:
Given
When True strain
at 
When True stress
=346.2 MPa
true strain
=0.226
We know

where
=True stress
=true strain
n=strain hardening exponent
k=constant
Substituting value


Divide 1 & 2 to get


Taking Log both side

n=0.973
