[Thermodynamic Application] Convert emision factor => units of grams/joule

Click For Summary
SUMMARY

The discussion focuses on converting the sulfur dioxide (SO2) emission factor from 0.80 lbm/(million Btu) to grams per joule. Participants emphasize the importance of dimensional analysis as a method for unit conversion, suggesting that users apply conversion factors systematically to achieve the desired units. The conversion process involves recognizing the relationships between pounds, joules, and the relevant conversion factors to ensure accuracy in the final result.

PREREQUISITES
  • Understanding of dimensional analysis
  • Familiarity with unit conversion techniques
  • Knowledge of energy units (Btu and joules)
  • Basic principles of thermodynamics related to emissions
NEXT STEPS
  • Research conversion factors between pounds and grams
  • Study the relationship between Btu and joules
  • Explore dimensional analysis techniques in detail
  • Learn about sulfur dioxide emissions regulations and their implications
USEFUL FOR

Students in environmental science, engineers working on emissions standards, and anyone involved in energy production and regulation will benefit from this discussion.

Homework Statement


Hello everybody,
Can you help me solve this:
Coal-burning power plants convert the sulfur in the coal to sulfur dioxide
(SO2), a regulated air pollutant. The maximum allowable SO2 emission for new
power plants (i.e., the maximum allowed ratio of the mass of SO2 emitted per
input of fuel energy) is 0.80 lbm/(million Btu). Convert this emission factor to
units of grams per joule!

Thanks for the response :)
