A pelton wheel attains its operating speed of 800 rev/min% determine constant angular acceleration of pelton wheel
2πf=εt
ε=2πf/t.
f=800 rev/min= 800/60 rev/s.
You need time of the motion ”t”
Please help me with solution to this problem
To determine the constant angular acceleration of a pelton wheel, we need to know two things: the initial angular velocity and the final angular velocity.
In this case, the initial angular velocity is 0 rev/min because the pelton wheel has not started moving yet. The final angular velocity is given as 800 rev/min.
Angular acceleration (α) can be calculated using the formula:
α = (ω_f - ω_i) / t
where ω_f is the final angular velocity, ω_i is the initial angular velocity, and t is the time taken to reach the final angular velocity.
Since the initial angular velocity is 0, the formula simplifies to:
α = ω_f / t
Now, in the problem statement, it is not mentioned how long it takes for the pelton wheel to reach its operating speed. Therefore, we cannot determine the constant angular acceleration without this information.
If the time taken to reach the final angular velocity is provided, we can substitute the values into the formula to find the constant angular acceleration of the pelton wheel.
Please provide the time taken to reach the final angular velocity in order to determine the constant angular acceleration.
