Answer: defination: It is defined as the ratio of the difference between maximum and minimum angular speeds of the flywheel to the mean speed of the flywheel during the cycle. Generally denoted as Cs. Formula: Cs = (Nmax – Nmin) / N.
What is the coefficient of fluctuation of speed?
The difference between the maximum and minimum speeds during a cycle is called the maximum fluctuation of speed. The ratio of the maximum fluctuation of speed to the mean speed is called the coefficient of fluctuation of speed.
What is coefficient of fluctuation of energy?
Explanation: Coefficient of fluctuation of energy: It is the ratio of the maximum fluctuations of energy to the work done per cycle.
Which of the following is are function’s of a flywheel?
Which of the following are functions of flywheel? Explanation: Flywheel provides uniform motion by storing energy during idle positions and using this at actual operational time and thus reducing the power capacity of the electric motor.
What is the coefficient of steadiness?
Explanation: Coefficient of steadiness is defined as the ratio of mean speed to the ratio of maximum fluctuation of speed, hence it is the reciprocal of coefficient of fluctuation of speed. therefore coefficient of fluctuation = 2/3 = 0.66.
What is coefficient of fluctuation of energy and coefficient of fluctuation of speed in flywheel?
(ii) Coefficient of fluctuation of energy: Coefficient of fluctuation of energy may be defined as the ratio of the maximum fluctuation of energy to the work done per cycle. It is denoted by Ce. Mathematically, Ce = Maximum fluctuation of energy/ Work done per cycle.
What is maximum fluctuation of energy in flywheel?
Explanation: The maximum fluctuation of energy in a flywheel = ΔE, mean kinetic energy of the flywheel = E, and coefficient of fluctuation of speed = Cs. ΔE = 2*E*Cs ⇒ 2000 = 2*E*0.02 ⇒ E = 50 kN-m/s.
What is fluctuation of energy and speed?
Fluctuation of speed: It is the difference between the maximum and minimum speed of Flywheel. Fluctuation of speed = (N1 – N2) rpm N1 – maximum speed, N2 — minimum speed Fluctuation of energy: It is the difference between the maximum and minimum energy of Flywheel.
How do you size a flywheel?
1) COUNT THE NUMBER OF DRILLED AND TAPPED HOLES ON YOUR FLYWHEEL. 2) MEASURE THE DISTANCE FROM THE CENTER OF ONE DRILLED AND TAPPED HOLE TO ANOTHER (MEASURING ACROSS THE CENTER LINE OF THE CRANK SHAFT) [DIMENSION “C”].
What are the types of flywheel?
Following are the types of flywheel used in vehicle:
Solid disc flywheel.Rimmed flywheel.High-velocity flywheel.Low-velocity flywheel.
What is flywheel in mechanical engineering?
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed.
Why flywheel is called flywheel?
Answer: FLYWHEEL = Fly + Wheel or basically “A wheel that goes fast”. A flywheel is the main wheel of the motor, it used to be the one motor that turned and gave energy to all other belts. For safety many belts fly overhead where no one could be accidentally pulled through and killed.
Which of the following is not a characteristic of the rope brake dynamometer?
4. Which of the following is not a characteristic of the rope brake dynamometer? d) Energy can be either utilized to do work or can be reused. Explanation: Rope brake dynamometer is an absorption dynamometer hence all the energy is absorbed by frictional resistances and gets converted into heat.
Is mean speed of the prime mover is increased in the coefficient of fluctuation of speed will?
The coefficient of fluctuation of speed remains same with any change in the mean speed of the prime mover.
Which of the following systems produce a vibration in the foundation?
Which of the following systems produce a vibration in the foundation? Explanation: It has been observed that when an unbalanced machine is installed on the foundation, it produces vibration in the foundation which needs to be countered to create smooth working of the machine. 2.
