Air flows through a circular pipe with variable cross section as shown. The pipe diameters shown are D₁ = 10 cm and D₂ = 5 cm. A water manometer at section 1 indicates h₁ = 20 cm. The outlet of the pipe is open to the atmosphere and elevated by H = 40 cm relative to section 1 height. The density of air is 1.2 kg/m³ and that of water is 1000 kg/m³. The gravitational acceleration is g = 9.81 m/s². The air flow is incompressible, inviscid and steady. All losses in the pipe are negligible. Neglect pressure variations with height in air. Find velocity at section 1 (V₁) in m/s. Enter V₁ in m/s below. air Atmosphere
