Explain how to solve :

Dear Student,
Here in this case from the given data we can write that ,

        Since,

        P = P₀ - ρgh = 98 × 10³ N/m²

        P₀V₀ = PV

        10⁵[A(500 - H)] = 98 × 10³[A(500 - 200)]

        H = 206 mm

        Level fall = 206 - 200 = 6 mm

        Hence, level fall = 6 mm
