Hi, I did some reading up on the basic math for jet aircraft,
thrust-to-weight ratio, and related concepts. I was trying to relate
this understanding to propeller driven aircraft, like a small
single-prop plane. When I see the stats for these small planes in
magazines, the engine horsepower is listed, along with the power loading
and empty weight.

I was wondering if it was possible, without diving too deeply into the
math and details, to roughly figure out the lbf that can be generated by
a propeller with, say, a 100 hp engine. Maybe by making a bunch of
simplifying assumptions, like a typical propeller, standard barometric
pressure, and such like?
