# Centripetal/radial velocity in a water tank.

• Kwetla
In summary, to calculate the magnitude of the effective centripetal velocity of the probe, you will need to consider the angular velocity, radius of the circle, and mass of the probe. You can use the formula V = ωr to calculate the centripetal velocity. It is possible that the probe may also experience some radial velocity, but this can be accounted for in the calculation. Good luck!

Hi,

We are running an experiment where we pull a velocity measuring probe through water at certain speeds to calibrate it.

However, our linear motor broke, so we have to try and use our rotary one instead.

We've set the probe up so that it gets pulled round in a circle at a set angular velocity, but my question is this:

Is it possible to calculate the magnitude of the effective centripetal velocity that the probe would experience? i.e the velocity of the probe being pulled to the centre?

Would it even experience a radial velocity? I think that it would...but I'm not sure how we could calculate it so that we could remove it.

!

Hello,

Thank you for sharing your experiment with us. It is definitely possible to calculate the magnitude of the effective centripetal velocity that the probe would experience. To do so, you will need to consider the following factors:

1. Angular velocity: This is the rate at which the probe is being pulled in a circular motion. It is usually measured in radians per second (rad/s). You will need to know the exact value of the angular velocity in order to calculate the centripetal velocity.

2. Radius of the circle: This is the distance from the center of the circle to the probe. It is usually measured in meters (m). You will need to measure or know the radius in order to calculate the centripetal velocity.

3. Mass of the probe: This is the weight of the probe, measured in kilograms (kg). The mass of the probe will affect the magnitude of the centripetal velocity.

Once you have these three factors, you can use the following formula to calculate the centripetal velocity:

V = ωr

Where V is the centripetal velocity, ω is the angular velocity, and r is the radius.

As for your question about whether the probe would experience a radial velocity, it is possible that it would experience some radial component of velocity as it is being pulled towards the center of the circle. However, this can be accounted for in the calculation of the centripetal velocity.

I hope this helps and good luck with your experiment!

## 1. What is centripetal/radial velocity in a water tank?

Centripetal/radial velocity is the velocity at which an object moves in a circular path within a water tank. It is a measure of the speed and direction of the object as it moves towards the center of the tank.

## 2. How is centripetal/radial velocity calculated?

Centripetal/radial velocity can be calculated using the formula v = rω, where v is the centripetal velocity, r is the radius of the circular path, and ω is the angular velocity.

## 3. What factors affect centripetal/radial velocity in a water tank?

The factors that affect centripetal/radial velocity in a water tank include the speed of the object, the radius of the circular path, and the angular velocity. Other factors such as the density and viscosity of the water may also have an impact.

Centripetal/radial velocity and acceleration are directly related to each other. As the velocity increases, the acceleration also increases, and vice versa. This is because acceleration is the rate of change of velocity, and in a circular motion, the direction of velocity is constantly changing.

## 5. What are the applications of measuring centripetal/radial velocity in a water tank?

Measuring centripetal/radial velocity in a water tank can have various applications. It can be used to study the behavior of objects in circular motion, such as the motion of planets around the sun. It can also be used in industries to optimize the design of machinery that involves circular motion, such as turbines and centrifuges.
