As much steam as possible from engine exhaust gas + warm water?

[QUOTE="russ_watters, post: 6850254, member: 142"] Water is a chemical. What I'm saying is you have constituents input and output at certain temperatures and mass flow rates, and it's just a fairly simple mixing problem to determine the desired result from the starting conditions. Since we've been given limited information on the parameters, I'd just start by calculating how much energy you can recover by cooling the exhaust gases down to 100C and then calculating how much water that amount of energy will boil. That will establish your maximum potential flow rate of water/steam generation rate. No, the first question has to be to define the process. If you don't know what you think you can get from the process then there's no way to know what the heat exchanger should look like. This will severely limit the amount of help we can provide and value of the work you are doing. This isn't a place where people get laughed at for being ignorant - educating people (fixing ignorance) is the entire point of the forum. But a couple of things: 1. If you are trying to do mechanical/electrical energy recovery with a steam turbine, please know that this is already a thing that's been invented. Broadly, it is used for electricity production in many cases, and specifically it's at least been demonstrated in cars: [URL]https://www.press.bmwgroup.com/global/article/detail/T0012212EN/more-efficiency-instead-of-power-loss:-bmw-group-research-and-engineering-is-using-combined-heat-and-power-in-a-car-for-the-first-timenhancing-efficiency-by-up-to-15-percent-feasible-1-5-litres-of-petrol-less-consumption-realistic-in-mid-range-car-basis:-the-principle-of-the-steam-engine?language=en[/URL] 2. You can't do it with atmospheric pressure steam and you can't use an open heat exchanger. [/QUOTE]
