Thermodynamic problem

  1. Sep 9, 2010 #1
    A rigid vessel of volume 0.1185 m3 contains one kg of steam‐water mixtures at 5 bar. If heat is
    added to the vessel until the pressure reaches 20 bar. Sketch a suitable state diagram to represent the process.



    How do i draw the state diag since pressure is not constant? So is this a case of constant volume?

    I think the system is a closed one.So only energy can be transferred against the boundary.Assuming heating ,since the container is rigid the problem must be solved as a constant volume process.

    agreed with the pukb's statement. the "rigid vessel" itself gives u the answer.
