Can you explain the set up of how to solve for the mass flow rate of position 3, the flow rate leaving the condenser?  I do not require the entire solution, just the set-up. This is a distillation column problem, and all enthalpies are provided, almost all mass fractions are provided as well, but no flow rates were given.

correct question answer get upvote 860. What are neutron moderators and their role in optimizing reactor design and operation?

illustrates an endothermic reactor applied in the production of methanol. Design a P&ID for this reactor by considering that the reactor temperature and pressure are needed to be maintained at a specific value.
