Here is my physics problem as listed in other threads: How long will a BBQ LP can last (how long can one make it last) @ output of 2HP constant? Physics steam problem: Pic on wimkin 2-27-'23: All presumptions approximate, with sizes of tubes and openings TBD. “As built” with operational measurements of effective RPM also accepted. A- LP tank pressure reduced to workable constant, from regulator or valve opening. B- LP pressure (in flow) 50 PSI, @ 1 Gal/HR(?). C- “Solder mix tip (from small solder tank set to start), above ambient pressure not required. D- Ignition E- Slight pressure flame chamber; 250F constant?. F- Venturii effect to mix and heat water (-10 PSI under ambient,@ 20 gal/hour @ about 200F) G- Pressure stroke (50 PSI x 2 sq. in. = 100 lbs?). H- Water tank (with water separator in exhaust feed available). I- water shut off/flow control. J- Pre-absorbtion pressure tank; size TBD, to allow steam pressure to build enough volume to fill piston chamber at the required RPM (200F, 50 PSI, slightly more volume than piston chamber. K- Exhaust both pressure and temperature close to ambient (the better). Size and materials limited. L- Pressure stabilizer/holes in intake valve [for flame maintenance]. M- Former spark plug / optional injection for late materials experiments.
