How long does it take a 19 kW steam engine to do 6.8 x 10^7 J of work?

If you could help, I would greatly appreciate it. Thanks!

How does a clutch on a steam engine work (Tractor/train/car)?

How does a clutch on a steam engine work. I am looking for a 10.0 ratio 1 speed transmission with a clutch so it will disengage at slow or stopped speeds.
Thank you
I actually had that I can not use a centrifugal clutch due to the slow speed of the engine in the original question but took it out. It will be running 10 rpm max (20 strokes per minute) 3 strokes a second. But will produce over 5 tons of power. What I need to know is what they use in a steam engine as a clutch to harness the massive amount of power. I can use a Eaton Fuller (semi) transmission that will provide the ratio and holding power(it should if only used in 1st and reverse..should) but want to look into what trains used as a more reliable option.
I meant 1 stroke (12″) every 3 seconds but you get the idea slow

How long does it take a 21kW steam engine to do 5.7×10^7 joules of work?

answer in units of seconds

Steam moves into the cylinder of a steam engine at a constant pressure and does 0.84 J of work on a piston.?

The diameter of the piston is 1.6 cm, and the piston travels 2.1 cm. What is the pressure of the steam?

How does a steam engine give positive work output at constant rate?

When the water is heated to become pressurized steam, it drives the piston, doing so there is some steam removed from the system with each cycle of the piston, eventually the boiler is left with less amount of steam/water mix, and pressure drops, to raise pressure back again, either the amount of heat inflow shall be raised or the water shall be brought back into the system.
How is it possible to continuously add water in a pressurized system without stopping and without consuming the same amount of energy that is being driven out of the drive piston???

How do steam locomotive smoke deflectors work?

I’ve seen that some have smoke deflectors, and others don’t. How do they work? Is it to compensate for funnel design? Does it apply aerodynamics and push the smoke away?

How does the automatic bell ringer on a steam locomotive work?

Most of the steam locomotives I’ve seen require the fireman to pull a cord attached to the bell, thus ringing it, however I’ve started seeing locomotives with automatic bell ringers; the fireman does not touch the cord but the striker in the bell automatically, rhythmically strikes the bell. How do these automatic bell ringers work?
