A venturi meter is a device for measuring the speed of a fluidwithin a pipe. The drawing shows a gas flowing at a speed v2through a horizontal section of pipe whose cross-sectional area A2= 0.0800 m2. The gas has a density of ? = 1.40 kg/m3. The Venturimeter has a cross-sectional area of A1 = 0.0300 m2 and has beensubstituted for a section of the larger pipe. The pressuredifference between the two sections is P2 - P1 = 170 Pa.
(a) Find the speed v2 of the gas in the larger original pipe.
1 m/s
(b) Find the volume flow rate Q of the gas.
2 m3/s
