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

In summary, the conversation is about converting the maximum allowable SO2 emission for new power plants from 0.80 lbm/(million Btu) to grams per joule. It is suggested to use a method of unit conversion, such as dimensional analysis, to solve the question.

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 :)

You have to show your attempts at solving the question to receive help. This is a forum policy.

For sure you were show some method of unit conversion, most likely some variant of dimensional analysis, with multiplying given number by conversion factors that cancel to 1. Have you tried to apply it to the question?
 

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

1. What is an emission factor in thermodynamics?

An emission factor in thermodynamics refers to the amount of pollutants or emissions released per unit of energy produced or consumed. It is typically measured in units of mass (such as grams) per unit of energy (such as joules).

2. How is an emission factor calculated?

An emission factor is calculated by dividing the total amount of emissions or pollutants produced by the total amount of energy consumed or produced. This calculation can be done for a specific process or for an entire system.

3. What units are used to express an emission factor?

An emission factor can be expressed in various units, but the most common unit used is grams per joule (g/J). This unit represents the mass of emissions released per unit of energy consumed or produced.

4. What is the importance of converting an emission factor to units of grams/joule?

Converting an emission factor to units of grams per joule is important because it allows for easier comparison and analysis of emissions across different processes or systems. It also provides a standardized unit for reporting emissions data.

5. How can an emission factor be used in practical applications?

An emission factor can be used in various practical applications, such as estimating the environmental impact of a process or system, determining the efficiency of energy production or consumption, and developing strategies for reducing emissions. It can also be used in regulatory and policy-making processes related to environmental protection and sustainability.
