Fluid properties of a diesel exhaust

AI Thread Summary
Kinematic viscosity data for combustion exhaust from diesel generators is sought for exhaust system design. The discussion suggests using the properties of the primary constituents of diesel exhaust, such as carbon dioxide (CO2), carbon monoxide (CO), or nitrogen (N2), as a basis for calculations. It is noted that focusing on the predominant gas simplifies the process, especially since specific gas properties are more readily available at elevated temperatures. This approach allows for effective estimation of fluid flows in exhaust systems despite uncertainties in the exact chemical makeup of diesel fuel.

Hello,

Anyone know where I can get fluid properties (specifically kinematic viscosity) of the combustion exhaust form a diesel generator (i am designing an exhaust system and I need to calculate fluid flows). I am not sure the exact chemical makeup of the diesel fuel. An estimation would be fine.

Thanks!

ok, can I do it like this..

diesel is a hydrocarbon...can I just base the fluid properties of the largest constituent? That is, assume the exhaust is 100% of the predominant gas since Its easier to find properties of specific gases at higher temperatures, let's say CO or N2?
 
CO2 is probably the predominant exhaust gas

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
