*69. ssm A Venturi meter is a device that is used for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v, through a horizontal section of pipe whose cross-sectional area is Az = 0.0700 m². The gas has a density of p = 1.30 kg/m². The Venturi meter has a cross-sectional area of A, = 0.0500 m² and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P, – P, = 120 Pa. Find (a) the speed v, of the gas in the larger, original pipe and (b) the volume flow rate Q of the gas. Hi Lo P1 A2 v2 A2 v2 A1 Venturi meter
