5. 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 20°C, at the rate of 20 tonnes per hour through the 5cm diameter pipe assuming the
pump is 70% efficient.
