A venture meter has a throat of 80 millimeter and is set in a horizontal water main of 150 millimeter diameter. If the measured pressure heads are 13.7 millimeter in the main and 10.5 millimeter in the throat, determine the flow rate in the pipe. Given: discharge coefficient for the meter is 0.98; gravitational acceleration is 9.81 m/s2.
