Gasoline (rho = 680 kg/m3 and v = 4.29 × 10–7 m2/s) is transported at a rate of 240 L/s for a distance of 2 km. The surface roughness of the piping is 0.03 mm. If the head loss due to pipe friction is not to exceed 11 m, determine the minimum diameter of the pipe using the third Swamee–Jain formula.
