Adiesel cycle has a compression ratio of 20, and the heat input qin to the working fluid is 1600 kj/kg the diesel cycle is unthrottled, so at the start of compression p 101 kpa and ti 298k. assuming the working fluid is air with constant properties, what is the maximum pressure and temperature in the cycle, the cycle efficiency, and imep? 1. 1.3 and e 1.0 kj/kg k

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?
