  1. CE 3231 - Introduction to Environmental Engineering and Science Readings for Next Class: Chapter 1.3 Ohio Northern University Chemistry, Microbiology & Material Balance Introduction Water & Air Pollution Env Risk Management Material Balance II – Mass Flow Developing a mathematical understanding of a system helps in predicting how a system will be have under a given circumstance. Developing a mass balance is often the first step engineering students take into mathematical modeling and a skill that is applied throughout engineering. Here we examine mass flow.

  2. Lecture 16Mass Flow(Material Balance II)

  3. Flow Balance

  4. Mass Flow A 10 L water sample is filter through a glass fiber filter into a filter vessel. The sample is filtered at a rate of 250 mL/min. The water sample being filtered has an initial total suspended solids concentration of 50 mg/L. The filtered water has a total suspended solids concentration of 2 mg/L. How much of the suspended solids accumulated on the filter within ten minutes?

  5. Mass Flow

  6. Mass Flow with Reaction Chlorine is being used as a disinfectant in a natural spring pool with a volume of 100 m3. Chlorine is introduced into the pool by a dropper. The concentration of chlorine in each drop is 10 mg/mL and the dropper is added to the pool at a rate of 0.1 mL per minute. The steady-state flow out of the pool to a nearby stream is 200 L/min, which is also the same as the flow rate of water into the pool. The chlorine in the pool also reacts with organic mater in the pool and disappears at a rate of 0.05 /min. The water flowing out of the pool has a chlorine concentration less than 1 mg/L. What is the concentration in the pool assuming the pool is mixed?
