These models are used to predict the effects of human activities on the environment, such as climate change, pollution, and resource depletion. 1 / 10 1. what is the maximum possible efficiency for an OTEC system? A. 5% B. 8% C. ~11 % D. 16 % 2 / 10 2. In a non-steady-state Continuous Stirred Tank Reactor (CSTR) model, which factor most significantly impacts the rate of change of pollutant concentration? A. Reactor volume B. Difference between inflow and outflow rates C. Initial pollutant concentration D. Reaction rate constant 3 / 10 3. When modeling pollutant dispersion in a river, what key assumption does the Plug Flow Reactor (PFR) model make about mixing? A. Complete and instantaneous mixing along the entire river length b) B. No mixing occurs along the river length C. Mixing is uniform but gradual along the river length D. Mixing only occurs at specific points along the river 4 / 10 4. What is the primary limitation of using steady-state models for environmental systems? A. They are only applicable to small-scale systems B. They are too complex to be solved analytically C. They cannot account for changes in environmental conditions over time D. They require extensive data collection 5 / 10 5. Which of the following factors does NOT directly influence the rate of pollutant generation in a water body? A. Water temperature B. Volume of the water body C. Pollutant concentration in the inflow D. Dissolved oxygen concentration 6 / 10 6. Which of the following is NOT a key component of a mass balance equation for a pollutant in an environmental system? A. Rate of pollutant generation within the system B. Rate of diffusion of the pollutant within the system C. Inflow rate of the pollutant D. Outflow rate of the pollutant 7 / 10 7. How does the Earth’s radiation balance contribute to the greenhouse effect? A. By increasing atmospheric pressure B. By reflecting solar energy C. By emitting long wavelengths D. By absorbing all radiation 8 / 10 8. In the context of air pollution modeling, what does the term “residence time” refer to? A. The time it takes for a pollutant to be removed from the atmosphere by natural processes B. The time it takes for a pollutant to react with other chemicals in the atmosphere C. The average time a pollutant molecule remains in a specific region of the atmosphere D. The time it takes for a pollutant to travel from its source to a receptor location Residence time is a measure of how long a pollutant persists in a given area before being removed or transformed. 9 / 10 9. What is the significance of the reaction rate coefficient in modeling pollution problems? A. It determines the size of the pollution source B. It represents the rate of pollutant removal C. It controls the flow rate of fresh air D. It influences the generation and decay of pollutants 10 / 10 10. Which law governs the diffusion of pollutants in both air and water? A. Boyle's Law B. Charles's Law C. Fick's Law D.
