Water is to be drawn from a reservoir for irrigation. The pipeline (length = 485 m, absolute roughness = 8.2×10-3cm) will discharge freely at a point 4.9 m below the surface of the reservoir. If a flow rate of 1500 gal h-1 is required, calculate the minimum diameter of pipe which must be used if the water is to be drawn without pumping. Changes in kinetic energy of the fluid may be neglected. [25]Density of water = 1000 kg/m3Viscosity of water = 1.42×10-3 kgm-1s-11 gallon = 4.545×10-3 m3Acceleration due to gravity = 9.81 m s-2
