Problem 1 Oil, with density of 900 kg/m³ and kinematic viscosity of 0.00001 m²/s, flows at 0.2 m³/s through 500 m of 200-mm-diameter cast-iron pipe (roughness: 0.26 mm). Determine the head loss (in m) and pressure drop (in kPa) if the pipe slopes down at 10° in the flow direction. Assume α = 1.0 throughout.
