Is there a way you can calculate exhaust flow using intake flow and exhaust temp? Maybe I would need fuel quantity as well. I just need a rough idea.. It's for on a diesel.
The chemical composition changes, too.the air is just heated way up so the only thing that changes is pressure right?
The number of moles can change, but density has to stay the same (if the volume is constant).Density stays the same since the moles of air in there is the same as before
Average of what?But I guess the exhaust gas temp is an average temp and would work.
Okay.Average temp of the gas flowing out of the engine.
How does the number of moles change? I realize the diesel adds some but does it add a significant amount?
Should be a bit more due to the reaction I posted.Using the Ideal Gas Law I end up with the same CFM going into the engine as going out.
RightHowever, putting in the different air temperatures mean the pressure going out is much higher.
Exhaust flow refers to the amount of exhaust gas that is expelled from a diesel engine. It is important because it directly affects the performance and efficiency of the engine.
The exhaust flow for a diesel engine is typically calculated using the engine's displacement, speed, and air-to-fuel ratio. Other factors such as turbocharger efficiency, exhaust valve size, and exhaust valve timing may also be taken into account.
The main purpose of calculating exhaust flow for diesel engines is to ensure that the engine is operating at its optimal level of performance and efficiency. It also helps in determining the appropriate size of exhaust components such as pipes and mufflers.
The exhaust flow of a diesel engine can be affected by a variety of factors including engine size, speed, air-to-fuel ratio, and load. Other factors such as engine temperature, fuel quality, and exhaust system design can also play a role.
There are several ways to improve exhaust flow for diesel engines, such as using a more efficient turbocharger, optimizing the air-to-fuel ratio, and upgrading the exhaust system components. Regular maintenance and cleaning of the engine and exhaust system can also help improve exhaust flow.
