Gasoline ( = 680 kg/m 3 and v = 4.29 10 -7 m 2 /s) is

Gasoline (ρ = 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 10 m, determine the minimum diameter of the pipe.
