Thermodynamic Properties Flashcards
1
Q
What is specific volume?
A
v = V / m
Where
V : Volume
m : Mass
2
Q
How is the quality (dryness fraction) of steam defined?
A
x = (m_vapour) / (m_total)
Where
m_vapour : Mass of vapour
m_total : Total mass
3
Q
What is Gibbs free energy?
A
G = H - TS
Represents the maximum work that can be obtained from a system at constant pressure and temperature.
4
Q
How is enthalpy change related to heat transfer?
A
Q= ΔH
For constant pressure processes.
5
Q
What is the relationship between R, cp and cv?
A
cp - cv = R
