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.
Carbon dioxide can be separated from other gases by preferential absorption into an amine solution. The carbon dioxide can be recovered by heating at atmospheric pressure. Suppose pure CO2 vapor is available from such a process at 80°C and 1 bar. Sup..
Are the values of ak from part (c) what you would expect for this signal? Justify your answer clearly. (f) Suppose you wish to model the signal now with p = 3. Write the normal equations for this case.
