Answer:
( a ) The specific volume by ideal gas equation = 0.02632
% Error = 20.75 %
(b) The value of specific volume From the generalized compressibility chart = 0.0142
% Error = - 34.85 %
Explanation:
Pressure = 1 M pa
Temperature = 50 °c = 323 K
Gas constant ( R ) for refrigerant = 81.49
(a). From ideal gas equation P V = m R T ---------- (1)
⇒ =
⇒ Here = Specific volume = v
⇒ v =
Put all the values in the above formula we get
⇒ v = ×81.49
⇒ v = 0.02632
This is the specific volume by ideal gas equation.
Actual value = 0.021796
Error = 0.02632 - 0.021796 = 0.004524
% Error = × 100
% Error = 20.75 %
(b). From the generalized compressibility chart the value of specific volume
= v = 0.0142
The actual value = 0.021796
Error = 0.0142 - 0.021796 =
% Error = × 100
% Error = - 34.85 %
