Steam engines are just like hydraulics. It's pressure on a given size and number of pistons X speed. HP=(TXS)/ 5252

@01Toecutter not sure if it'll help but piston steam engines usually have max Torque at/near 0 RPM.Max Torque proportional to piston area, and boiler pressure. "crank" geometry alters component of force "made" by pistons that gets converted to torque.While steam able to get in/out of the piston freely at low RPM torque remains fairly flat. Higher rpm and piping and valves will restrict flow of steam somewhat, and as so the "starting" pressure in the cylinders drop,so does torque.

@chezgreens Not like hydraulics when steam is being used expansively, as it should be to max efficiency. That equation's only correct with 0% cut off, ie steam inlet valves are open for 100% of the power stroke. or if using a mean effective pressure found some other way (by measuring power and working backwards, or from indicator diagram), If you can alter the valves to shut before the pistons reach the end of their strokes. steam will be used more efficiently for only a small drop in power

What are the torque specs? And at what rpm? Thank you

[1BustedMyth]

Hmmm... I like!

[steveBB30]

How are you rating the hp- guessed, calculated from indicator diagram, or measured from a prony brake, or electrical generation?

An idea about how big these engines would add loads to your videos. it needn't be much- a ruler left in front the engine, or some other "common" standardised object such as drinks can is all that's needed to provide a visual clue

With all the parts flinging around in there what kind of MTBF will these engines get?
