Post #1 has too many links to read through and it is not clear why you have included them.

However, in the model answer for Example 9.60, the author uses $V_1= 0.0024m^3 (=2.4L)$ which, as you say, is incorrect. (I get $V_1 = 2.514L$.) Presumably that's the problem about which you are asking.

So it looks like a simple mistake by the author.

$$r_c=\frac{V_3}{V_2}$$
