A filling station uses a Venturi tube to measure the flow rate of gasoline. The density of the gasoline is = 7.70 ✕ 102 kg/m3, the inlet and outlet tubes, respectively, have a radius of 2.74 cm and 1.37 cm, and the difference in input and output pressure is P1 − P2 = 1.20 kPa. Find the speed (in m/s) of the gasoline as it leaves the hose and
Find the fluid flow rate in cubic meters per second.
