Apr 11, 2011· They established that 34.5 lb of water was evaporated in one hour to make one mechanical Hp in the steam engines, and Boiler Horsepower was defined by ASME in 1884 as “the thermal output required to evaporate 34.5#/hr of water from and at 212°F. So now it makes sense to me how the term Boiler HP was derived.
