The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (? = 7.00 102 kg/m3) through a hose having an outlet radius of 2.88 cm. The difference in pressure is measured to be P1 ? P2 = 1.60 kPa and the radius of the inlet tube to the meter is 1.44 cm.
(a) Find the speed of the gasoline as it leaves the hose.
m/s
(b) Find the fluid flow rate in cubic meters per second.
m3/s
