Need some help here. Not sure what I'm trying to find.
A fuel pump sends gasoline from a car's fuel tank to the engine at a rate of 7.81x10-2 kg/s. The density of the gasoline is 732 kg/m3, and the radius of the fuel line is 2.99x10-3 m. What is the speed at which gasoline moves through the fuel line?
