Unformatted text preview: From table A.3 ρ air 0.4292 ρ SL ⋅ = ρ air 0.526 kg m 3 = We also have from the manometer equation ρ air8000 g ⋅ Δ z 8000 ⋅ ρ air3000 g ⋅ Δ z 3000 ⋅ = where the numerical subscripts refer to conditions at 3000m and 8000m. Hence Δ z 8000 ρ air3000 g ⋅ ρ air8000 g ⋅ Δ z 3000 ⋅ = ρ air3000 ρ air8000 Δ z 3000 ⋅ = Δ z 8000 0.909 0.526 100 × m ⋅ = Δ z 8000 173m =...
