Honestly, a conductor of the same size throughout its length will give you excellent flow in any case. I you gradually decrease the size toward the outlet, you'll end up with faster moving air.
Increasing the flow rate depends purely on the amount of air being pushed or pulled through the...
I'm building a shop out of cast concrete pieces and 8'' schedule 80 pvc pipe donated by the city after their recent water service expansions. I'm casting all the concrete pieces myself and the pipe will serve as support columns for the roof. and everything can be shipped on a flatbed tractor...
I get the idea but the first portion of your statement didn't make a lot of sense. Other than that, here's pro to reducing the ''Engine driven charging system''. You're not using the engine to charge the batteries! That means your reducing the load on the one component in a hybrid that uses a...
I got to say man, this thread has gotten crazy. Other than that, the exhaust intake events don't last very long at all at 8k rpms. The boosted intake charge would definitely aid in flushing the dirty exhaust gases out. and there would only be boost for as long as the intake port was open. Once...
Use carbon fiber tubes to build the duct and housing. Saves weight. Aluminum or glass filled nylon would make a nice lightweight turbine. And last but not least, replace that steel rimmed spare tire with an alloy wheel. Besides that, think on this, if you reduce the demand on the engine driven...
On another note, forgot to explain the to reason for the air duct exiting in the rear valence. A car traveling at any speed is constantly diverting air and creating pressure differentials. At the rear of the car is an extreme low pressure area which would aid in removing the air flowing through...
Try this on for size: If an air duct were to run the length of the cars body with an inlet in the grille and the outlet located somewhere in the rear valance you would have a good solid path for the air to be diverted through. If you inserted a lightweight turbine in the airstream, it would...
If the wall is thick enough you could drill at least one hole through the wall of the pipe to intersect the location of the outer race, assuming this is a sealed roller bearing. You could then tap the hole with an appropriate thread for a small socket head set screw. Position the bearing where...
