1. The problem statement, all variables and given/known data 0.025kg of steam at a quality of 10% and a pressure of 2 bar is heated in a rigid container until the temperature reaches 200 degrees celcius. find the final quality (x). 2. Relevant equations 3. The attempt at a solution ok, so i use the steam tables and find vf and vg at 2 bar, and therefore work out the intial volume. since the container is rigid, there is no change of volume so this should also be the final volume.how do i get the final value of vg[/B] (i'm assuming vf is 0 since steam is superheated at 200 degrees celcius)?.
