To construct a nonmechanical water meter, a 0.550 T magnetic field is placed across the supply water pipe to a home and the Hall voltage is recorded. (a) Find the flow rate in liters per second through a 3.40 cm diameter pipe if the Hall voltage is 70.0 mv. 3.39E-3 X L/ (b) What would the Hall voltage be (in V) for the same flow rate through a 14.0 cm diameter pipe with the same field applied? X V
