em. There are four worksheets that make up this simulation that follow this w em (Base System) em with a Flash System (Case Study System) ther values on the diagram will change to reflect the alterations. Changes in with the purpose being to keep the solid flowrate constant. There are two sh lations of steam table values on them. These can be accessed by unhiding th re included for ease of comparison for a sensitivity analysis. Sensitivity of th s in input liquor temperature and solids content was investigated. These Flo equired, the Case Study System Flow Diagram should be altered.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
