Moving the topic slightly, there's an article in this month's EIM about
Walschaerts valve gear. hear the author mentions a 0.010 inch lead. My
question is this: Would such a small lead make that much difference even
though it is a non negligible portion of the valve travel? Is it fair to
consider steam as totally fluid on such a macro scale, and wouldn't
turbulent effects etc mitigate against small differences just as 12 inch
to the foot steam, small orifices gave 'wire drawing' effects akin to
increasing supoerheat?
