Entropy change is evaluated using Eq. 6.2a based on an internally reversible process. Can the entropy change between two states
of a system be determined for any process linking the two states whether reversible or not?
1 answer:
Answer:
YES
Explanation:
Entropy is an extensive property of the system entropy change that value of entropy change can be determined for any process between the states whether reversible or not. i have attached the formula to calculate entropy change which is independent of whether the system is reversible or not and can be determined for any process.

Answer:
The shear strain is 0.05797 rad.
Explanation:
Shear strain is the ratio of change in dimension along the shearing load direction to the height of the plate under application of shear load. Width of the plate remains same. Length of the plate slides under shear load.
Step1
Given:
Height of the pad is 1.38 in.
Deformation at the top of the pad is 0.08 in.
Calculation:
Step2
Shear strain is calculated as follows:
For small angle of ,
can take as
.
Thus, the shear strain is 0.05797 rad.
Answer:
Head loss=0.00366 ft
Explanation:
Given :Water flow rate Q=0.15
= 6 inch=0.5 ft
=2 inch=0.1667 ft
As we know that Q=AV
So
=0.687 ft/sec
We know that Head loss due to sudden contraction
If nothing is given then take K=0.5
So head loss
=0.00366 ft
So head loss=0.00366 ft
