Properties are those observable characteristics, such as pressure, temperature, or volume, that define the equilibrium state of a thermodynamic system. Properties do not depend on how the state of a system is attained; they are only functions of the state of a system. Therefore, properties are independent of the path by which a system reaches a certain state. We can categorize properties as extensive and intensive. 1 Extensive Properties The value of an extensive property depends on the extent or the size of a system.

2 kg water per 1kg dr y solids 7. 2 kg per 1 kg dry solids. 8. The feed is 1000 kg/h. Various streams have been labeled along with the known composition values on the diagram. Note that the composition of each stream is in terms of solids and water only. Stream C is divided equally into streams E and G. Product P, with 80% solids, is the desired final product. Stream K produces a by-product at the rate of 450 kg/h with 20% solids. 10 a. Calculate the mass flow rate of product P. b. Calculate the mass flow rate of recycle stream A.

11, is useful to study pressure–temperature relationships between various phases. This 28 CHAPTER 1 Introduction diagram gives the limiting conditions for solid, liquid, and gas (or vapor) phases. At any location within the areas separated by the curves, the pressure and temperature combination permits only one phase (solid, liquid, or vapor) to exist. Any change in temperature and pressure up to the points on the curves will not change the phase. 11, the sublimation line separates the solid phase from the vapor phase, the fusion line separates the solid phase from the liquid phase, and the vaporization line separates the liquid phase from the vapor phase.
