Problem 16.26

The figure below shows cascade temperature control of a polymerization reactor, which uses feed heat exchange to adjust the reactor temperature. Using the instrumentation diagram, explain how this cascade control system (both master and slave components) handles the following disturbances. (describe what happens to the reactor temperature.) Assume normal temperatures of coolant (70F), polymerization feed (200F), exchanger effluent (100F), and reactor outlet (800F). (a) Feed temperature becomes too high. (b) Feed flow rate becomes too high. Master r----~--------1 Slave Coolant Polymerizer feed Figure E16.26

Derivation of the Bernoulli Equation (the missing steps) The Bernoulli equation as derived in Monday’s CHE377 lecture consisted of a number of steps, including two (relativelysimple) steps thatwereomitted at the start.
