MORNING SAMPLE QUESTIONS to the well pump. The engine has a 10.5:1 compression ratio and delivers 200 hp while running with a Questions 132-133: A rural irrigation system uses a 350-in-displacement V8 engine to provide power wide-open throttle at 4,200 rpm. At these conditions, the air intake to the engine is 400 cfm, and the brake specific fuel consumption is 0.65 lbm/(hp-hr). The heating value of 75.0-degree API gasoline is defined by the formula HV= 18,320 + 40 (API-10) Btu/lbm. Engine friction at these operating conditions is 50 hp. The engine operates on a four-stroke cycle. The density of the fuel is 42.8 lbm/ft³. 132. At these operating conditions, the delivered torque (lb-ft) to the well pump is most nearly: (A) 4.2 (B) 250.1 (C) 500.2 (D) 1,571.4 133. The ideal Otto cycle efficiency for this engine is most nearly: (A) 25% (B) 49% (C) 61% (D) 81%
