An orifice meter is to be installed in a 12 cm ductile iron pipe carrying water at 27oC. A mercury manometer is to be used to measure the pressure difference across the orifice when the expected velocity is 3.2 m/s. The manometer scale reads 12 mm Hg. Determine the appropriate diameter of the orifice. The density of the manometer fluid is 850 Kg/m3 while the density of water at 27oC is 993 Kg/m3. Assume C to be 0.61. Answer: 0.1204 m
