Question

Task 4 a) An oil with a density of 870 kg/m³ and kinematic viscosity of 10.7 mm²/s flows at a rate of 0.1 m³/s through a galvanised iron pipe 100 mm diameter. The oil flows over a distance of 1000 m and the pipe has a slope in 1 in 500. Determine the (i) loss of head using two different approaches/equations and comment on any differences/assumptions. [Marks: 10 out of 100] (ii) pressure drop as the oil flows over the full distance of 1000 m. [Marks: 4 out of 100] b) Using a diagram of \"Head\" vs \"Discharge\" discuss the key aspects that need to be considered for the hydraulic design of a pumping mains [Word limit: 500 words] [Marks: 6 out of 100]
