A nonmechanical water meter could utilize the Hall effect by applying a magnetic field across a metal pipe and measuring the Hall voltage produced. What is the average fluid velocity in m/s for a 4.25 cm diameter pipe, if a 0.575 T field across it creates a 60.0 mV Hall voltage?

The velocity is  

Explanation:

From the question we are told that  

   The diameter of the pipe is  

    The magnetic field is  

     The hall voltage is  

Generally the average fluid velocity is mathematically represented as

=>      

=>      

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
