P.4.8 Oil of viscosity 10 mN s/m2 and density 950 kg/m' is pumped 8 km from an oil refinery to a distribution depot through a 75 mm diameter pipeline and is then dispatched to customers at a rate of 500 ton/day. Allowance must be made for periods of maintenance, which may interrupt the supply from the refinery for up to 72 hours. If the maximum permissible pressure drop over the pipeline is 3450 kN/m2, what is the shortest time in which the storage tanks can be completely recharged after a 72 hour shutdown? The roughness of the pipe surface is 0.05 mm. Ans. 27.6 days
