An electromagnetic flowmeter is used to measure the average flow rate of a liquid in a pipe of diameter 60 mm. The flux density in the liquid has a peak value of 0.2T. The output from the flowmeter is taken to an amplifier of gain 1100 and input impedance of 2 MΩ. If the impedance of the liquid between the electrodes is 300 kΩ, then the peak value of the amplifier output voltage (in V) for an average flow velocity of 40 mm/s is.
