The Venturi tube discussed in Example 14.8 and shown in figure may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (p = 7 X10² kg/m³) through a hose having an outlet radius of 1.2 cm. If the difference in pressure is %3D measured to be (P1 - P2 = 1.2 kPa) and the radius of the inlet tube to the meter is 2.4 cm. (a) Find the speed V2 of the gasoline as it leaves the hose. (b) Find the fluid flow rate in cubic meters per second.
