Re: How do we ensure two liquids at different temperatures are mixed properly?5 June 2012 at 1:29pm
The answer to this question is simple and not the desired one. If a small quantity of warm biodiesel fuel is added to a tanker truck 80% full of 25 degree diesel, the added quantity of biodiesel will rapidly approach the tanker temperature of 25 degrees. Even with rapid mixing, some portion of the biodiesel can always drop below 32 degrees somewhere in a large quantity of 25 degree diesel. No computer model or comprehensive calculation is needed. The only way to assure that the biodiesel temperature never goes below 32 degrees it to assure that the tanker trucker of diesel is always above 32 degrees when the biodiesel is added.
