How do you calculate the peripheral speed when you know the rpm and radius of the blade?

After 1 revolution, the blade tip has travelled 2πr units of length (feet, metres etc)
So just multiply this figure by the number of revolutions per minute to get the peripheral distance travelled in a minute.
Bear in mind that this will give the answer if feet/metre per minute and you may then want to convert this into mph or kph.

How do you calculate speed moving around the curve?
To calculate the speed of an object moving around a curve, you can use the centripetal acceleration formula: (a = v^2 / r), where (a) is the centripetal acceleration, (v) is the speed of the object, and (r) is the radius of the curve. To find the speed ((v)), you need to know the radius of the curve and the centripetal acceleration acting on the object.
How do you calculate the turning radius of a car?
I don't recall the exact formula, but, it involves the car's speed and the car's tires slip angle at a given speed.
How do you calculate schwarzcschild radius?
The Schwarzschild radius, rs, is given by rs = 2Gm/c2 where G is the gravitational constant, m is the mass of the object, and c is the speed of light in vacuum.
What is the centrifugal force on a turbine blade if a London bus is hanging from the blade?
A ball park figure for the weight of a double decker bus might be about 15,000 kilograms. But to calculate the centrifugal force on a turbine blade with this hanging from it would require the blade length and the rotational speed of the turbine.
Which vision is first affected by fatigue drugs and speed?

What additional information does Hannah need in order to calculate the tangential speed of the orbiting object?
To calculate the tangential speed of an orbiting object, Hannah would need to know the distance from the object to the center of the orbit (radius) and the time taken for the object to complete one full orbit. With this information, she can use the formula for tangential speed, which is tangential speed = 2Īr / T, where r is the radius and T is the time taken for one orbit.
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
How is rotational speed affected by the radius?
Rotational speed is inversely proportional to the radius. A smaller radius will result in higher rotational speed, while a larger radius will result in lower rotational speed. This relationship is described by the equation v = rĪ, where v is linear speed, r is radius, and Ī is angular velocity.
How is tangential speed affected by the radius?
Tangential speed is directly proportional to the radius. As the radius of an object increases, its tangential speed also increases. This relationship is described by the equation v = rĪ, where v is tangential speed, r is the radius, and Ī is the angular velocity.
How does change in radius effect the linear speed?
The linear speed is directly proportional to the radius of rotation. An increase in radius will result in an increase in linear speed, while a decrease in radius will result in a decrease in linear speed. This relationship is governed by the equation v = Ī * r, where v is linear speed, Ī is angular velocity, and r is radius.
How do you find angular speed without radius?
Angular speed is calculated by dividing the linear speed by the radius. If the radius is unknown, you would not be able to directly find the angular speed without more information about the motion.
What is the centripetal acceleration of a stone with a radius of 0.75 meters and a height of 1.5 meters and travels a horizontal distance of 4 meters?
I don't think you have enough information. Here are two formulae to calculate centripetal acceleration: a = v2 / r a = omega2 x r (omega is the angular speed, in radians per second) Basically, apart from the radius you also need to know (or have enough information to calculate) the speed (or equivalently, the angular speed).
