Homework Answers
jet engine is an example: A basic principle of physics called the law of conservation of energy tells us that if a jet engine needs to make more power each second, it has to burn more fuel each second. A jet engine is meticulously designed to hoover up huge amounts of air and burn it with vast amounts of fuel (roughly in the ratio 50 parts air to one part fuel), so the main reason why it makes more power is that it can burn more fuel.
Regenerative Braking is also an example in 4 strategies to recover energy.
Segway is an example but with many uncertainties.
In case of any doubt, please do comment.

2. A dc chopper is used for regenerative braking of a separately excited dc motor. The dc supply voltage is 400V. The motor has ra=0.2 ohms. Km=1.2 V-s/rad. The average armature current during regenerative braking is kept constant at 300A with negligible ripple. For a duty cycle of 60% for a chopper , determine a) Power returned to the supply. b) Minimum and maximum permissible braking speeds and c) Speed during regenerative braking.

The two-quadrant chopper is used to control the speed and regenerative braking mode of a DC motor with a motor constant of 0.1 V/rpm, and Ra = 0.2 ?. Consider a ripple free current. The chopping frequency is 250 Hz and the supply voltage is 120-V dc. S2 and D2 are operated for regenerative braking of the motor. At the speed of n = 350 rpm and an average output current of -100 A. (a) Determine tON. (b) Draw waveforms...

The diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor without any work or heat interactions. Calculate the velocity at the exit of a diffuser when air at 100 kPa and 30°C enters it with a velocity of 358 m/s and the exit state is 200 kPa and 90°C. The specific heat of air at the average temperature of 60°C = 333 K is cp = 1.007 kJ/kg·K.
