1. Oil that has a density of 880 kg/m flows under a head of 30 m. The pipe that the oil flows through is 3000 m long and 0.35 m in diameter. Due to the cooling along the span of the pipe the viscosity changes, this may be taken as 0.57 kg/m-s over the first 1500 m and 1.14 kg/m-s over the second 1500 m. Confirm that laminar flow conditions exist and calculate the flow in dm/s. Neglect entry and exit losses. Answer 37.185 dm/s

1. Oil that has a density of 880 kg/m3 flows under a head of 30 m. The pipe that the oil flows through is 3000 m long and 0.35 m in diameter. Due to the cooling along the span of the pipe the viscosity changes, this may be taken as 0.57 kg/m-s over the first 1500 m and 1.14 kg/m-s over the second 1500 m. Confirm that laminar flow conditions exist and calculate the flow in dm/s. Neglect entry and exit losses. Answer 37.185 dm'/s
