Introducing the Effects of Mixing into the Energy Balance
In Section 12.1 we restricted the discussion and examples to the standard state (25°C and 1 atm). In this section we proceed with what happens when the temperatures of the inlet and outlet streams differ from 25°C for a binary mixture in an open, steady-state process. (For a closed system the initial and final states of…

Heats of Solution, Dissolution, and Mixing
Up to this chapter we have assumed that when a stream consists of several components, the total properties of the stream are the appropriately weighted sum of the properties of the individual components. For such ideal solutions, we could write down for the heat capacity of an ideal mixture, for example,Cpmixture=xACpA+xBCpB+xCCpC+… or, for the enthalpy,ΔH^mixture =xAΔH^A+xBΔH^B+xCΔH^C+⋯ In particular,…
