An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 100 kPa and 17°c, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Determine (a) the maximum temperature and pressure that occur during the cycle, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (e) Also, determine the power output from the cycle, in kW, for an engine speed of 4000 rpm (rev/min). Assume that this cycle is operated on an engine that has four cylinders with a total displacement volume of 1.6 L. Assume constant Cv = 0.716 kJ/kgK and k=1.4.

A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 36 km/h at the 76-m mark. He then maintains this speed for the next 61 meters before uniformly slowing to a final speed of 31 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Part 1 Answers: (a) al- Finish line Calculate (a) the magnitude of the tangential acceleration near start of the race and (b) the magnitude of the tangential acceleration near the end of the race.
