Soyabean oil is to be pumped from a storage tank to a processing vessel. The distance is 148m and included in the pipeline are six right-angle bends, two gate valves and one globe valve. If the processing vessel is 3m lower than the storage tank, estimate the power required to pump the oil at 20oC, at the rate of 20 tonnes per hour through the 5cm diameter pipe assuming the pump is 70% efficient
