Choose one of the project questions below and make the solution with computer suppont (MATLAB, Excel, etc.). P1. After the fresh feed solution of 10% trisodium phosphate (Na_(3)PO_(4)) by mass is mixed with the recycle stream, it enters an evaporator and its water is removed until its concentration becomes 34%Na_(3)PO_(4) by mass. This concentrated solution obtained is cooled to 20^(@)C in a crystallizer and 100kg of Na_(3)PO_(4).12H_(2)O crystals are obtained per hour. While 10% of the saturated solution coming out of the crystallizer is thrown out for cleaning purposes as purge stream, the remaining part is recycled and mixed into the fresh feed stream fed to the system. Accordingly, calculate the following; a) Mass of fresh feed sent to the
