A 3.81-cm diameter venturi meter is installed in a pipe with an internal diameter of 10.23 cm. A 127 cm manometer filled with mercury is used to measure the pressure difference across the venturi meter. If the manometer reads 101.6 cm when 15 °C water is flowing through the pipe, what is the flow rate of water (m3/min)? Assume that the venturi meter coefficient of discharge equals 0.98.
