Question

A mixture of ideal gases has the following composition by mass :

Oxygen(60%), Carbon dioxide(20%),Nitrogen(20%)

Calculate the Characteristic gas constant of the mixture in J/kg-K.

Step 1

We can calculate the Characteristic gas constant for mixture of gasses by using the following formula.

Step 2

Let Oxygen be gas1, Carbon dioxide be gas2 and Nitrogen be gas3.

Characteristic gas constant for gases 1,2 and 3 is calculated as follows

Step 3

Substitute m1=0.6; m2=0.2kg; m3=0.2kg, R1=259.81 J/kg-K, R2=188.95 J/kg-K, R3=...
