Chapter 8 and 9 – Energy Balances
CBE2124, Levicky 1 Chapter 8 and 9 Energy Balances Reference States. Recall that enthalpy and internal Energy are always defined relative to a reference state ( Chapter 7). When solving Energy balance problems, it is therefore necessary to define a reference state for each chemical species in the Energy balance (the reference state may be predefined if a tabulated set of data is used such as the steam tables). Example. Suppose water vapor at 300 oC and 5 bar is chosen as a reference state at which H is defined to be zero. Relative to this state, what is the specific enthalpy of liquid water at 75 oC and 1 bar? What is the specific internal Energy of liquid water at 75 oC and 1 bar? (Use Table B. 7). Calculating changes in enthalpy and internal Energy . H and U are state functions, meaning that their values only depend on the state of the system, and not on the path taken to arrive at that state.
