boiler per I.H.P.? A graphical illustration of the answer to the question Whatbecomes of the heat-units? is given in Fig. 24 for an excep-tionally economical engine. Of the 186,600 B.T.U. generated by burning coal on the gratethere is a loss of 10,000 units by radiation from the boiler; theremainder divides into two streams. About 70% is absorbed bythe boiler and the rest passes through an economizer on its wayto the chimney. The feed-water contains 5450 units when itreaches the economizer, and there it absorbs 15,750 more unitsthat otherwise would have been wasted. The heated feed-waterreceives the hot water from the jackets and delivers (after losingsome heat by radiation) some 27,650 units to the boiler. A totalthen of 159,250 units have been saved, and with small loss are ELEMEXTARY PRINCIPLES. 43 delivered to the engine. Here the losses are very great, only25,390 units being delivered by the engine. As this result isobtained in a record-breaking engine, the amount delivered in an
