A Venturi tube might be employed as a fluid flow meter. Assume that the device is employed at a service station to measure the flow rate of gasoline (p = 660 kg/m^3) via a hose having an outlet radius of 2.80 cm. When the difference in pressure is measured to be P1 - P2 = 1.20 kPa and the radius of the inlet tube to the meter is 1.40 cm.
(i) Determine the speed of the gasoline as it departs the hose.
(ii) Determine the fluid flow rate in cubic meters per second.
