Book Description
Excerpt from The Selection and Installation of Machinery for Small Pumping Plants The brake horsepower (b. H. P.) is the power delivered by an engine to the belt that drives a pump, or to the pump itself in case the unit is direct connected. For steam engines it is usually about 90 per cent of the indicated horsepower and for gasoline engines about 80 per cent. The same idea is expressed also by saying the mechanical efficiency of the engine is 90 or 80 per cent. The indicated or rated horsepower (i. II. P.) of steam engines is based on the power developed in the cylinder. This can be determined in an actual case only by means Of a steam engine indicator. However, experiments made by engine builders enable them to tabulate with sufficient accuracy the rated horsepower for engines Of given size of cylinder, with a given steam pressure and a given number of revolutions. The practice of all builders is not the same in this particular. Some state that an overload of 25 per cent is allowable, while others give the maximum power the engine is capable of indicating.
