Answer:
a).Control volume
b). 
= 502.416 J/kg-K
c). 
= 4.187 kJ/kg-K
d). 
= 87.91°C
Explanation:
a). It is a control volume system because mass is varying in the system.
b). Specific heat of nickel is = 502.416 J/kg-K
c). Specific heat of water is = 4.187 kJ/kg-K
d).We know that
net energy transfer = change in internal energy
= 87.91°C

Explanation:
Explanation:
The tear test determines the force required by a material to undergo complete failure when there is already a crack or tear present in it.
With this test we understand a material's resistance to failure when there is already a crack present.
The material which already has a crack is placed in a tensile testing or universal test machine. So, both sides of the material along the crack are pulled until material failure takes place.
Answer:
Explanation:
Hello,
In this case, for the inlet stream, from the steam table, the specific enthalpy and entropy are:
Next, for the liquid-vapor mixture at the outlet stream we need to compute its quality by taking into account that since the turbine is adiabatic, the entropy remains the same:
Thus, the liquid and liquid-vapor entropies are included to compute the quality:
Next, we compute the outlet enthalpy by considering the liquid and liquid-vapor enthalpies:
Then, by using the first law of thermodynamics, the maximum specific work is computed via:
Best regards.
