2. Which of the following is not a purpose of material balance? A. Determine the consumption quotas for raw materials to check whether the design requirements are met. B. Determine the production capacity of the installation. C. Serve as a basis for heat balance calculations. D. Determine the flow rates and compositions of inputs and outputs for each device, and use this information to select and design the equipment. The answers given by others online are B, but based on the content on page 1 of the association’s guidelines, which states that it is possible to determine the design scale and capacity of a factory’s production installations, can it be concluded that B is correct? I think to determine heat balance, material balance calculations are necessary, but they serve only as a basis rather than being the ultimate goal. Should the answer be C?
The third one must be correct. Heat balance is based on mass balance.
First there is production capacity, and then material balance, right?
Choose B; the original text can be found in Chapter 1 of the training book on material balance, which is the foundation of energy balance.
The third one must be correct. Heat balance is based on mass balance. Agree with this statement
B The rest are all exact quotes from the book! The production capacity of device B is determined by the process design, and it has nothing to do with material balance!
I also think B is the right choice; production capacity has nothing to do with balance, as all production is balanced.
Thank you all :) I’m not sure if there will be an exam this year; I’ll just keep studying for now. Hehe
