5. If you designed a part with an overall width dimension of 1.250 inches and printed it on the same 3D printer using the same f
ilament, what would you predict the width of the printed part would measure?
6. If the width of your part had to measure between 1.220 inches and 1.255 inches to operate properly, would you adjust the width dimension of your CAD model to improve the chances of the 3D-printed model being within these limits? Explain your reasoning.

Answer:
V1=5<u>ft3</u>
<u>V2=2ft3</u>
n=1.377
Explanation:
PART A:
the volume of each state is obtained by multiplying the mass by the specific volume in each state
V=volume
v=especific volume
m=mass
V=mv
state 1
V1=m.v1
V1=4lb*1.25ft3/lb=5<u>ft3</u>
state 2
V2=m.v2
V2=4lb*0.5ft3/lb= <u> 2ft3</u>
PART B:
since the PV ^ n is constant we can equal the equations of state 1 and state 2
P1V1^n=P2V2^n
P1/P2=(V2/V1)^n
ln(P1/P2)=n . ln (V2/V1)
n=ln(P1/P2)/ ln (V2/V1)
n=ln(15/53)/ ln (2/5)
n=1.377
