Flywheel Energy ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Flywheel Energy ಎಂದರೇನು?
Flywheel energy storage uses rotational inertia to store and release kinetic energy. It's used for power smoothing and peak shaving.
ಸೂತ್ರ
Power = dE/dt (rate of energy change)
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Calculate: E = 0.5 × I × ω² where I is moment of inertia, ω is angular velocity
- 2Energy stored = change in kinetic energy
- 3Power = dE/dt (rate of energy change)
Worked Examples
ಇನ್ಪುಟ್
Flywheel I=100 kg·m², ω=500 rad/s
ಫಲಿತಾಂಶ
E = 0.5 × 100 × 500² ≈ 12.5 MJ energy stored
Significant storage capacity
Common Mistakes to Avoid
- ✕Neglecting bearings friction losses
- ✕Over-sizing flywheel (excessive cost and weight)
Frequently Asked Questions
Why use flywheels over batteries?
Flywheels handle high power (charge/discharge rate); good for short-duration storage.
What limits flywheel speed?
Material strength; excessive speed causes material failure. Typically limited to 20-60% ultimate stress.
