Speed of Tip Calc: Rotor Diam 7.6m, 450 rev/min

In summary, the speed of tip calculator for a rotor with a diameter of 7.6m and rotating at 450 rev/min is approximately 2,406 meters per minute. The rotor diameter directly affects the speed of tip calculator, with a larger diameter resulting in a higher speed. 450 rev/min is a common speed for smaller wind turbines and other industrial applications. The accuracy of the speed calculation depends on the input variables and formula used. The speed of tip calculator can also be applied to other rotating objects, such as fan blades or propellers, as long as the input variables are known.

What equation relates both?

[tex] v = \omega r [/tex]
 
  • #3
the answer in the back of the book says179 m/s. but when i try that formula it comes out as 311.6

Oh sorry, yes the book is right

A rev is equal to 2 pi radians, and a minute is equal to 60 second. You need to homogenize (spl?) your units.

the rev/min is 47.81 rev/sec

sorry its 47.12 rad/s
 
  • #7
Multiply it with 3.8 m
 

What is the speed of tip calculator for a rotor with a diameter of 7.6m and rotating at 450 rev/min?

The speed of tip calculator for a rotor with a diameter of 7.6m and rotating at 450 rev/min is approximately 2,406 meters per minute. This calculation is based on the formula: speed = diameter * pi * revolutions per minute.

How does the rotor diameter affect the speed of tip calculator?

The rotor diameter directly affects the speed of tip calculator, as it is one of the variables in the formula for calculating speed. A larger rotor diameter will result in a higher speed of tip calculator, assuming all other variables remain constant.

Is 450 rev/min a standard rotation speed for a rotor?

The standard rotation speed for a rotor can vary depending on the specific application and design. However, 450 rev/min is a common speed for smaller wind turbines and is also used in other industrial applications.

How accurate is the speed of tip calculator for a rotor?

The accuracy of the speed of tip calculator for a rotor depends on the accuracy of the input variables and the formula used for calculation. Generally, this calculation is considered to be accurate for practical use in engineering and scientific applications.

Can the speed of tip calculator be used for other types of rotors or objects?

The speed of tip calculator can be used for any rotating object, as long as the input variables (diameter and revolutions per minute) are known. This calculation is commonly used in wind turbines, but can also be applied to other rotating objects such as fan blades or propellers.
