PROBLEM 3 - MULTIPLE EFFECT EVAPORATORS WPS 417 FALL 2008 - DUE 11/10/08 - CATHERINE CURR The data from 'STEAM TABLES' is used to calculate T, P, and l for steam and vapo The 'REPORT' workbook compares the output of various altered proposed cases. The base case, which is represented by the flowsheet diagram in 'FLOWSHEET', c evaporators. The given data is included on the flowsheet and is color coded by flo organized in a table in 'TABLES' and the order of calculations can be seen in 'CALC highlighted cells in the table and calculations represent data that is taken directly fr values can be altered in the flowsheet worksheet in order to change the output in th The proposed case, which is represented by the flowsheet diagram in 'FLOWSHEE 3-stage evaporators with a flash tank to flash the condensate from the first evapora with vapor from the second evaporator and creates the steam flow into the third ev is included on the flowsheet and is color coded by flow. The flowsheet output is or 'TABLES - P' and the order of calculations can be seen in 'CALCULATIONS - P'. T in the table and calculations represent data that is taken directly from the proposed values can be altered in the flowsheet worksheet in order to change the output in th highlighted cell represents data that is kept constant by the output of the base case can only be altered by changing the values in the base case flowsheet. To review the base case due to changes in flowsheet data, it is only necessary to a 'FLOWSHEET' and review the output in 'TABLES'. However, in order to make cha output, the changes must be made in 'FLOWSHEET - P' and then the directions in be followed to correct the circular reference.
