Problem 2.9:
A tank whose volume is 12 m3 contains 6.2 kg of water at 1.4 bar.
a) What is the phase (liquid, vapor, liquid/vapor mixture)?
b) What is the temperature?
c) We add more steam to the tank while maintaining its temperature constant at the value calculated in part b. As a result, the pressure in the tank increases. Determine how much water (in kg) of steam must be added to bring the steam in the tank to the point of condensation.
d) Draw a qualitative PV graph and show the path of the process for part c.
