Question
A Venturi 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 = 0.0721 m². The gas has a
density of p = 1.30 kg/m³. The Venturi meter has a cross-sectional area of A₁ = 0.0317 m² and has been
substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P₁ = 86.7
Pa. Find (a) the speed v₂ of the gas in the larger original pipe and (b) the volume flow rate Q of the gas.
