<u>B) Calculate the amount of work received from the paddle wheel </u>
assuming ideal gas situation
v1 = v2 ( for a constant volume process )
work generated by paddle wheel = system internal energy
dw = mCv dT . where ; Cv = 0.743 KJ/kgk
= 5 * 0.743 * ( 500 - 300 )
= 3.715 * 200 = 743 KJ
<u>C) calculate the amount of entropy generated ( KJ/K )</u>
S2 - S1 = 1.8983 KJ/K
attached below is the detailed solution
Answer:
Poissons ratio = -0.3367
Explanation:
Poissons ratio = Lateral Strain / Longitudinal Strain
In this case, the longitudinal strain will be:
Strain (longitudinal) = Change in length / total length
Strain (longitudinal) = (8.40392 - 8.4) / 8.4
Strain (longitudinal) = 4.666 * 10^(-4)
While the lateral strain will be:
Strain (Lateral) = Change in length / total length
Strain (Lateral) = (2.09967 - 2.1) / 2.1
Strain (Lateral) = -1.571 * 10^(-4)
Solving the poisson equation at the top we get:
Poissons ratio = -1.571 / 4.666 <u>( 10^(-4) cancels out )</u>
Poissons ratio = -0.3367
I think downwards as that's how most saw's work.
