A Venturi meter with an inlet diameter of 0.6 m is designed to measure a current with an average flow of 6 m3 /s of standard air. What is the required diameter of the bottleneck (restriction) if this flow corresponds to a reading of 0.10 m of alcohol on a differential manometer connected to the inlet and the restriction? Consider the specific mass of alcohol equal to 800 kg/m, the specific mass of standard air equal to 1.225 kg/m and that the system has no head loss. a P 11 h
