A gas station uses a Venturi tube to measure the flow rate of gasoline. The density of the gasoline is = 7.30 102 kg/m3, the inlet and outlet tubes, respectively, have a radius of 3.10 cm and 1.55 cm, and the difference in input and output pressure is P1 P2 = 1.20 kPa.

(a) Find the speed (in m/s) of the gasoline as it leaves the hose.

m/s

(b) Find the fluid flow rate in cubic meters per second.

m³/s
