Homework Statement
Hydroelectric power station's turbine has a diameter of 7.5m, and a rotation frequency of 94 rotations per minute. What is the turbine's blades acceleration?
P.S. This is translated from another language
Homework Equations
a=4π2Rn2
Where n=rotational frequency
The Attempt at a Solution
My understanding is that I need to convert rotations per minute, to rotations per second for the formula to work. Therefore: 94/60
Though when I plug that in the formula for n, I get a wrong answer.
I also divided the diameter by two to get the radius(R)
4*π2*3.75*(94/60)2≈363.37
The correct answer is 231.7m/s2
