Hi all,

I am new to this site and was referred to post my question on this forum.

I am in a slow process of building my own steam engine from the ground up and was hoping you can help me.

I’m now in the process of designing my boiler. As James Crank states in his article about modern steam, there are very few references left to learn how to design these steam vehicles.

I am trying to find the correlation between BHP and the amount of steam I require. I see that one bhp is equivalent to 34.5 pounds of water converted to steam. Unfortunately there is no direct relation between weight and volume.

At first I was assuming the calculation would be to find the volume of the cylinder multiplied by the rpm’s over a certain period of time and this would be the volume of steam I need, but how do I go from lb/h to volume?
How do I calculate the required steam needed from my simple piston engine, and essentially the size of boiler (bhp rating)?

Thank you all for your time,

Austin

One Lb of steam is one Lb of water.

If you don’t have a book of steam tables by Keenan & Keyes then this
on line calculator for saturated steam tables might help.
