2016 Chemistry Registration Exam Question 25
Thread Content
Does anyone think this problem is missing the heat transfer coefficient for benzene inside the pipe? How did you approach solving it? Could you provide a detailed solution process?
K is calculated based on the heat balance before the increase in flow rate, and then the heat transfer coefficient inside the pipe is determined
It seems possible; as the benzene flow rate increases, the heat transfer coefficient within the pipe also increases, while the steam heat transfer coefficient and the fouling thermal resistance remain unchanged. From this, K can be determined, and then the exit temperature can be calculated based on thermal equilibrium, right? Now the problems require a lot of calculation steps; there’s not even time to use a calculator
It shouldn’t be necessary. My calculation process is as follows; please correct me if there are any mistakes
