what is coefficient of fluctuation of speed

by Johnathan Wisozk Published 3 years ago Updated 2 years ago

(i) Coefficient of fluctuation of speed: Coefficient of fluctuation of speed is defined as the ratio of the maximum fluctuation of speed to the mean speed. It is denoted by C s. Mathematically, C s = (N 1 – N 2) /N Where, N 1 = maximum speed in rpm; N 2 =minimum speed in rpm; N = mean speed in rpm

Explanation: 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.

Full Answer

What is co-efficient of fluctuation?

Co-efficient of fluctuation is the ratio of the differance between minimum and maximim speed to the mean speed . Normaly this term is used to define a flywheel of a system . Get 5 credit points for each correct answer.

What is the reciprocal of coefficient of fluctuation of speed?

Coefficient of steadinessis reciprocal of coefficientof fluctuation of speed. Explanation: Coefficient of steadinessis defined as the ratio of mean speed to the ratio of maximum fluctuation of speed, hence it is the reciprocal of coefficientof fluctuation of speed. What is fluctuation of energy in flywheel?

What is the coefficient of fluctuation of speed in flywheel?

The coefficient of fluctuation of speed is a limiting factor in the design of flywheel. It varies depending upon the nature of service to which the flywheel is employed.

What is meant by maximum fluctuation of energy?

The difference between the maximumand minimum energies is called maximum fluctuation of energy. The co-efficient of fluctuationof speed is the ratio of maximum fluctuationof speed to the mean speed. The variations of energyabove and below the mean resisting torque line is known as fluctuation of energy.

What is the coefficient of fluctuation of speed and energy?

(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 meant by 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.

What is steadiness coefficient?

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.

What is the relation for the coefficient of fluctuation of speed in terms of maximum fluctuation of energy and the kinetic energy of the flywheel at mean speed?

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.

How do you calculate energy fluctuation?

In the case of N quanta the energy fluctuation of the system is (Δε)2 = N(Δε1)2, i.e.

What is the coefficient of fluctuation of energy in a flywheel?

= ω 1 + ω 2 2.

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.

How do you find the coefficient of speed?

0:252:44Coefficient Of Fluctuation Of Speed - YouTubeYouTubeStart of suggested clipEnd of suggested clipYou will get this. Alright now we know that Omega is proportional to n. Isn't it so I can say that nMoreYou will get this. Alright now we know that Omega is proportional to n. Isn't it so I can say that n can be replaced by omegas you will have 2 into Omega. 1 minus Omega 2 by Omega 1 plus Omega. 2.

How do you calculate the maximum fluctuation of energy of a flywheel?

Maximum fluctuation of energy in a flywheel is equal to [where I = Mass moment of inertia of the flywheel, E = Maximum fluctuation of energy, CS = Coefficient of fluctuation of speed, and ω = Mean angular speed = (ω₁ + ω₂)/2]

Which is used to reduce the fluctuation of speed and which is used to control the speed variations caused by the varying load?

Explanation: Flywheel: A flywheel is used to control the speed variation caused by the fluctuations of energy during each cycle of operation.
