Question

A refinery uses a Venturi tube like the one shown in the figure to monitor the flow of gasoline (ρ = 7.00  10² kg/m³) through a hose. The inlet radius of the Venturi tube is 1.90 cm,the outlet radius is 1.20 cm, and the difference in pressure measured by the two gauges is

P₁ − P₂ = 1.40 kPa.

(a) Determine the speed of the gas as it leaves the Venturi tube.
m/s

(b) Determine the volume flow rate of the gasoline.
m³/s
