Problem 2.7:
An eight-liter pressure cooker contains a mixture of steam and liquid water at 2 bar. Through a level indicator we can see that the liquid occupies 25% of the volume inside the cooker. a) What is the temperature inside the cooker? b) What is the total mass of water (liquid plus vapor) in the cooker? c) What is the mass fraction of the liquid? d) The cooker, while it remains sealed, is placed under running water until its temperature cools to 25 °C. What is the pressure in the cooker? e) What force does it take to unseal the cooker? The cover is circular with a radius of 20 cm.
Develop the dynamic model for this system as functions of time for any given variation in inputs.

A paper by Ruckenstein and Tsai (1981)* shows that an "optimum pore size" can exist for catalytic reactions of large solute molecules in solvent-filled pores. Obtain the paper from your library and read it carefully. Then derive the analytical equati..
When dried to remove theremaining water (but not the water of hydration), the final dry Na2S2O2· 5H2O crystals must not contain more than 0.1 %impurity. To meetthis specification, the original solution, before cooling, is further diluted with wate..
