Aventuri meter is a device 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 = 0.0510 m2. the gas has a density of rho = 1.30 kg/m3. the venturi meter has a cross-sectional area of a1 = 0.0381 m2 and has been substituted for a section of the larger pipe. the pressure difference between the two sections is p2 - p1 = 81.0 pa. find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate q of the gas.
