Solving questions for the Registered Chemical Engineer exam
Thread Content
I’m working on questions 13-17 on page 360 of the lower volume of the Basic Examination for Registered Chemical Engineers; I don’t know how to calculate them to determine that the answer is A. The answer is indeed A, so I’m asking experienced experts for help. Thank you very much!
2000*0.99/0.95=2084.2
Reply to 2# yzt2005: I don’t think so; shouldn’t this X be a raw material? It is the raw material multiplied by the yield that gives the amount of product; so how is it that the resulting value represents the quantity of the product?
Pure product obtained: 2000*0.99. Plant yield = Pure product obtained / Pure product that should be obtained from the raw materials used in production (i.e., the actual pure product produced) = 0.95. The result is obvious. . .
