M.E. BOARD FEBRUARY, 1951 In a certain diesel- alactric power plant, diesel generator set has the following data Diesel fuel consumption Electric power generated at switch boerd--- -S18,000 kw Direct Number of generat ing hours ---- 595 hrs Assume 90% generator efficiency and 80 % excita- tion efficiency Determine: ....-109,495 kg excilation -: ...-3946 kw-hr 1. Total BHP load of the engine 2. Pounds of fuol per kw-hr 3. Pounds of fuel per BHP-hr l4. With nominal out put rating of 1520 HP, at what load percent engine capacıty. 5. Circulating water enter's the diesel engine at 80 F and leaves at 110 F. Assuming that this operation, 0.15 gal per min. of cool ing water per BHP is circulated, what percent of heat energy if fuel with HV of 19,000 Btu/Ib is used. 6. The has its rated run is taken by círculating water the brake ther mal efficiency
