Document Summary

Crib: 2 pages, 8. 5 x 11, both sides. Energy: accumulation = generation + heat transfer r. Vr delta h term is usually not 0, so need to add/remove heat to maintain desired t we have time dependence, so we can expect to have some exponential solution simplify. How do we deal with pfr (other extreme, no mixing) Simplify like heat transfer design eqn for pfr similar to batch reactorthis is because prf = like lot of mini batch reactors on conveyer belt. Pfr has wrt z, while batch reactor has wrt t make sure you know what assumptions are being made in each design eqn. Or can also divide one eqn by the other. B. c. (1) @ z = 0, ca = ca0, t(z = 0) = t0 (2) @ z, t = t, ca = ca still can"t solve this analyticallyneed to do numerically. Heat is added at different rates throughout the reactor length to maintain constant t.
