Q. A venturi meter is installed to measure the flow rate of water in a 178 mm diameter (ID) pipe. The throat diameter is 102 mm. The differential pressure measured using a manometer is 154.3 kN/m². The data given are:

discharge coefficient = 0.98; water density = 1000 kg/m³. The volumetric flow rate of water (in m³/s) is                           .

Ans: 0.145 to 0.155
