Specific Volume of a Mixture

If you wish to obtain the specific volume of a mixture, it is necessary to use another approach, since the procedure above works only for pure substances. This time, use one of the units and specify the stream into the unit. The calculation will tell you the specific volume. 

Find the specific volume of a mixture consisting of 630 kmol/h of carbon monoxide, 1130 kmol/h of water, 189 kmol/h of carbon dioxide, and 63 kmol/h of hydrogen at 1 atm and 500 K. The specific volume is the solution to the Redlich-Kwong equation of state, Eq. (2.8). 

Step 2 If the bottom of the screen does not show the units, use the View/Model Library pull-down menu or press the FIO key.

Step 9 You can obtain the specific volume by dividing the volumetric flow rate by the molar flow rate, 46449/2012 = 40.98 m /kmol. To obtain Table 2.1 in spreadsheet format, place your cursor in the upper-left cell of the Stream table, copy down to the lower-right cell, copy, and paste into Excel. You can also have the Stream Table copied to the flowsheet, and it can be copied from there as a picture.
