Answer:

The velocity is $v =2.455 \ m/s$

Explanation:

From the question we are told that

The diameter of the pipe is $d = 4.25 \ cm = 0.0425 \ m$

The magnetic field is $B = 0.575 \ T$

The hall voltage is $V_H = 60.0 mV = 60 *10^{-3} \ V$

Generally the average fluid velocity is mathematically represented as

$v = \frac{V}{ B * d }$

=> $v = \frac{60*10^{-3}}{ 0.575 * 0.0425 }$

=> $v =2.455 \ m/s$

We will apply the equation:
2as = v² - u²
v = √(2as + u²)
v = √(2 x 4 x 400 + 13²)
v = 58 m/s

hope this helps
