   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?
