Question details

3. The following specifications of a diesel engine are given Engine Speed (rpm) Torque (ft-lbf) Fuel Consumption (gal/hr) 1200 1600 20 a. Compute the fuel consumption in gallons per day for an average engine speed of 1200 rpm, assuming that the engine works 16 hours per day. (8 pts). b. Compute the engine horse power at 1200 rpm (8 pts). c. When this engine works at an average speed of 600 rpm, the fuel consumption rate is 12 gal/hr, and the efficiency of the engine is 25%. Compute the Torque of this engine when running at 600 rpm (8 pts). d. Calculate the efficiency of a midsize sedan driving at 50 mph and 25 mile per gallon fuel consumption rate, while the engine runs at 60 lb-ft torque at 2500 rpm. Gasoline density and specific heating value are 6.1 Ibm/gal is 19000 BTU/lbm. (8 pts).
