To construct a nonmechanical water meter, a 0.500-t magnetic field is placed across the pipe supplying water to a home, and the hall voltage between the ends of a pipe diameter perpendicular to the field is measured. this works, because water contains ions, which are charged particles and move at the flow speed of the water.
a) find the flow rate, in cubic meters per second, through a 2.4-cm diameter pipe if the hall voltage is 62.5 mv.
b) what would be the hall voltage, in volts, for the same flow rate through a 12.5-cm-diameter pipe with the same field applied?
