An old water-supply pipeline contains a long segment that is horizontal and 30 cm in diameter. A leak along an inaccessible portion of the buried pipeline is highly likely. A pair of pressure located upstream of the leak indicate a pressure drop of 23,000 N/m2. Another pair of pressure gauges located downstream of the leak indicate a pressure drop of 20, 900 N/m2. The distance between the gauges in each pair is 100 m. determine the magnitude of the leak. Assume minor Je negligible and that the water temperature is 20°C.
