Chapter 18: Models for Nonideal Reactors

Additional Homework Problems

CDP18-HB

On August 19,1973, a barge on the Mississippi River was damaged, spilling 140,000 gal of chloroform into the river. The following data were taken at a point 16.3 miles downstream from the spill

Properties of the Mississippi River (averages):

Volumetric Flow = 268,000 ft3/s
Velocity = 1.26 mph
Width = 4000 ft
Depth = 36.3 ft

  1. What is the mean time a molecule spends traveling between the spill and the concentration monitoring site? (Ans: 216 h)

  2. Based on the flow rate, what is the shortest time until you would expect detection downstream?

  3. [Part (c) is a D-level problem] Develop a model that fits the data. Evaluate the model parameters.
