Lubricating oil at 20°C with a density of 871 kg/m³ and a kinematic viscosity of 1.5 x 105 m²/s flows horizontally in a steady, laminar manner through an annulus of inside radius R₁ = 0.04 m and outer radius of R = 0.06 m. The annulus is 1.0 m long. Find the energy loss per unit mass and pressure loss for a fully developed flow of 0.00005 m³/s. ghL= APL = N.m/kg N/m²
