Document Summary

Due: wednesday, february 5, 2020: reactors and conversion. The easiest way to make dough is to put flour into water in order to bind the proteins in the flour together to make gluten, the protein that gives bread its unique texture. Plug in for r f to get -kc f = dc f /dt. Integrate to get ln c f = -kt + constant. Given c f = c f0 at t = 0, ln (c f /c f0 ) = -kt. Plug in for r f to get c f0 v - c f v = kc f v. Plug in c f0 = 1, v = 0. 01, c f = 0. 02, k = 0. 01. Solve to get v = 49 l c. d. Plug in for r f to get -kc f = v dc f /dv. Integrate to get ln c f = -kv/v + constant.
