A thin oil having a density of 800 kg/m³ is pumped from an underground storage tank through a 300 mm diameter pipeline to the tank of a fuel station. Gate valves have been used for flow control. The horizontal distance between the two tanks is 6.3 km while the elevation of the tank in the fuel station is 7 m above that of the underground storage. The viscosity of the oil is 0.0018 N-s-m². The roughness of the inner surface of the pipe is 0.75 mm. The flow rate through the pipe is 0.22 m/s. (a) Design a pipe system for oil transportation and show your design with a diagram. (b) Calculate the friction loss in the pipes. (c) Calculate the power required to drive the pump if the pump has an efficiency of 75%.
