- round 4 dec. places, subject: powerplant A four-stroke, 8 cylinder diesel engine with bore and stroke of 9 inches and 12 inches respectively and speed of 950 rpm has a brake mean effective pressure of 164 psi. The specific fuel consumption is 0.39 lb/bhp-hr and the fuel heating value is 18,500 Btu/lb. Determine the brake power (HP) and the mass of fuel used (lb/hr).20. A regenerative braking system stores kinetic energy of a car so that it can be recovered when the vehicle resumes moving. One way to do this is to “store” the energy in a spinning flywheel. One such design uses a solid disk flywheel with moment of inertia 0.040 kg m2 and maximum rotation rate 45000 rpm. (a) What is the maximum energy storage? (b) In principle it could store the kinetic energy of a 1700 kg car moving at what speed before braking? (c) If this energy is used to start the car moving again in 10.0 s, what is the power output of the system?The minimum bearing life is the life that 10% of bearings will achieve or exceed before they fail due to fatigue. Select one: True False
- I what direction is the force acting on the shaft associated with rotation of mass imbalance for constant speed rotation19 Rigidity depends on what 3 factors? Gravity, radius of Gyration and direction of spin. Mass of the rotor, radius of gyration, & speed of spin. Wander, drift and speed of spin. Mass of the rotor, distance to spin axis, & direction of spin. 20. The pilot of this aircraft pulls the control column back to start a climb. She makes no change to the engine power. The aircraft loses speed as it converts potential energy into kinetic energy. The total amount of energy in the aircraft reduces. The aircraft's speed remains the same because the engine power is unchanged.
