When compressed liquid properties are unavailable for a substance, it is acceptable to use the ____ values at the same temperature
Select one:
a. saturated liquid
b. saturated vapour
c. critical
d. triple line
Hey, the answer is "Option a. Saturated Liquid".
Explanation: If you ever discover that the substance is in a
compressed-liquid state but, you
don't have a compressed table to find the desired thermodynamic
values then, all you have to do is use compressed-liquid
approximation and assume that the properties of compressed liquid
are same as those of the Saturated Liquid at the same
temperature.
Specific Internal Energy of compressed Liquid (T, P) ? Specific
Internal Energy of Saturated Liquid (T).
Specific Volume of compressed Liquid (T, P) ? Specific Volume of
Saturated Liquid (T).
Specific Entropy of compressed Liquid (T, P) ? Specific Entropy of
Saturated Liquid (T).
Specific Enthalpy of compressed Liquid (T, P) ? Specific Enthalpy
of Saturated (u_f(T)+P*v_f(T)).
u_f(T) = Specific Internal Energy at required Temperature.
P*v_f(T) = (P = P_sat, v_f(T) Specific Volume at required
Temperature).
Note: If your desired value falls between two different values then, you might have to use Linear Interpolation to calculate it out.
