For an oil-transportation truck, to fill an initially empty 275-gal tank with fuel oil requires 12 min. If the flow from the filling nozzle is steady, and the diameter of the filling nozzle is 20 mm, do the following: a) Write the mass conservation equation for this control volume case of the tank. (4) b) Find the steady volume flow rate of fuel oil into the fuel tank. (5) c) Estimate the velocity of the fuel oil exiting the filling nozzle.
