Hello
I am planning on building a 4" scale compound steam engine. Changing the linear scale by 1/3 affects area by a factor of 1/9 and volume scale by 1/27. Physics doesn't scale so I am concerned that changing the linear scale may require modifications to the steam path dimensions, especially on a compound engine.
Does the scaling require any non-scale modifications to the steam path?
eg. steam pipe bore dimensions, piston/cylinder dimensions, stroke etc.
