Using the compressibility factor chart below determine whether the contents are important). A 20.0 lbs propane tank liquid, gas or a mixture of liquid in equilibrium with its vapor. If the contents are vapor liquid in equilibrium with its vapor, calculate the specific volume of the vapor phase in units of m'/Kg. The critical pressure of propane is 42 atm, its critical temperature is 369.9 K and its molecular weight is 44.09 g/mol а or a 1.5 1.4 1.3 з000 Generalized compressibility factors (z 0.27) 15.00 12 1.1 т, 15.00 10.00-5.00 3.00 1.0 2.00 50 2.00 1.30 20 .80 O.80 85 0.9 0 gn0,95. 1.70 1.Io 00 60 Saturated gas 1.50 0.8 1.40 1.35 0.7 1.30 .25 0.6 T0.75 1.20 0.80 0.5 1.15 0.85 1.10 1.08 0.90 0.4 1.06 0.95 1.04 0.3 1.02 90 1.00 0.2 0 50 0.1 Saturated liquid 0 0.1 3.0 4.0 5.0 30 0.2 0.3 04 05 1.0 2.0 10 20 Reduced pressure, P Compressibility factor, z S0.90Question
