Water is flowing with a speed of 2 ms^-1 in a horizontal pipe with cross- sectional area decreasing from 2 × 10^-2 m^-2 to 0.01 m^2

Question

Water is flowing with a speed of 2 ms^-1 in a horizontal pipe with cross- sectional area decreasing from 2 × 10^-2 m^-2 to 0.01 m at pressure 4 × 10⁴ Pa. What will be the pressure at small cross-section

Answer 1

v₁ = 2ms^-1, a₁ = 2 x 10^-2m², a² = 0.01 m², P₁ = 3 x 10⁴ Pa; P₂ = ?; ρ = 10³ kg m^-3
