23. 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 v2 through a horizontal section of pipe whose cross-sectional area is A2 = m2. The gas has a density of 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P1 = 120 Pa. Find (a) the speed v2 of the gas in the larger, original pipe and (b) the volume flow rate Q of the gas.
