Question: A tubular heat exchanger with plug flow in the tube has steam at a constant temperature on the shell side. The system is initially at steady state with no temperature driving force, and the steam is introduced in a step to the shell.
(a) Determine the tube outlet temperature as a function of time. This will require analyzing a distributed-parameter model.
(b) Formulate a lumped-parameter model that would give an approximate result for the tube outlet temperature.
Refer to the tabulated values ofΔG°fin Appendix IVB in the textbook to calculate E°cell for a fuel cell that employs the reaction between ethene gas (C2H4) and oxygen to form carbon dioxide and water (gaseous).
What is the white precipitate that forms while the reaction mixture is heated. The reaction is the hydrolysis of the ester Butyl benzoate yields products 1-butanol and benzoic acid.
