Calculate the specific volume of helium using the compressibility factor. 500 kpa, 60 degrees celsius

Explanation:

Formula for compressibility factor is as follows.

                     z =

where,     z = compressibility factor for helium = 1.0005

               P = pressure

          = molar volume

                R = gas constant = 8.31 J/mol.K

                T = temperature

So, calculate the molar volume as follows.

                             =

                             = 0.0056

As molar mass of helium is 4 g/mol. Hence, calculate specific volume of helium as follows.

                           =

                           = 0.00139

                           = 0.00139

                                 = 1.39

Thus, we can conclude that the specific volume of Helium in given conditions is 1.39 .
