Ludic, thanks for your time and work on this educating video. Right now you have the tubes straight and parallel to each other. some of your torque are merely cancelling each other out. More important to the tubes being parallel to each other is the steam direction to be parallel; to the surface of the can from its exiting point! You can get maximum torque out of your steam tubes if you bend them 90 degrees and attach so that the direction of the steam exiting the tube will come out parallel to the circumference of the can and no torque will be wasted!...
Although my model had very low efficiency in converting heat energy into mechanical energy, it is interesting that the first piston steam engine developed by Newcomen was also only 2% efficient.
Great project. Could you explain, maybe in another video, why the air moves faster when the diameter of the tube gets smaller(Ventury effect)? Also a small mechanical engineering hint: Usually one would use at least 2 bearings per axle and fix them in a way, so that the axial movement of at least one bearing is limited to prevent the whole construction from falling apart. Press fitting doesn't count as fixed in this regard. Here are some examples from Wikipedia (sorry for not in English, but the images explain it pretty good): de.wikipedia.org/wiki/Datei:Fest-Los-Lagerung.svg de.wikipedia.org/wiki/Datei:Schwimmende-Lagerung.svg de.wikipedia.org/wiki/Datei:Stuetzlagerung-angestellt-X-linien.svg
Nice job. I built a Hero's steam engine that does 5400 RPM. (www.HeroSteamEngine.com with embedded RU-vid video). Thoughts about whether an aeolipile (Hero's steam engine) could have driven a car or train or do other useful work has been debated for a century or more. I decided to build one and measure its power output to settle the question. I calculated its theoretical efficiency at converting heat energy to mechanical energy and it was only about 1%. But when I built one I found that the efficiency was only 0.01%, possibly due to losses from friction and air resistance. The results are given in detail in the web site. Look it up to see video, photos, calculations, discussions and dispelling myths about Hero (Heron of Alexandria) himself.
Evan,thanks for the link to your very detailed and informative site on Hero's Turbine designs. I have a friends teenage grandson who is looking for some useful design information to assist with building a turbine. Your site will assist gteatly👍
@@howardosborne8647 I hope your friend finds some useful information. The calculations are all in the Appendices including calculating the thrust produced by a jet of steam once it reaches the speed of sound. That occurs at only about 10-20 psi.
