A2: Problem 1 Previous Problem Problem List Next Problem (2 points) Process Classification Consider this system: As part of the maple syrup production process. A d leaves the system. This then creates a concentrated maple sugar solution (maple syrup) which is removed and the process can then be repeated. ilute maple sugar solution is heated in an open tank, part of the water evaporates and a) Is the process of creating maple syrup from a dilute maple sugar soluion a batch, transient state process semibatch, transient state process continuous, transient state process batch, steady state process semibatch, steady state process continuous, steady state process b) Which term(s) in the general balance equation is/are relevant (meaning non-zero) to analyze the mass balance of water in the tank described above throughout one entire cycle of production, meaning the dilute solution entering the tank to maple suryp leaving the tank? Select all terms that are relevant A. input B, output C. generation D. consumption E. accumulation Note: You can earn partial credit on this problem Preview My Answers Submit AnswersExplanation / Answer
1) It is batch and transient process.
Batch because: No inflow and outflow of maple syrup during the process. Only when the evaporation is completed the entire batch of concentratted syrup is taken out
Transient because: The concentration of maple syrup inside the vessel changes with time
2) A, B and D
A(mass flow water coming in from dilute solution)
B(mass of water going out in concentrated solution)
D (mass of water going out as evaporated water)
