    Can anyone explain why the pressure at X = P2 + row g ( h + delta h )

    I understand the P2 is pressure at the surface but not the other part?

    The pressure caused by a fluid is :
    Pressure = ρg(Δh)
    ρ is the density of the air,
    g is gravitational acceleration,
    Δh is the height of the fluid (Which is equivalent to h+Δh in this situation)

    Therefore the total pressure at point X is
    (Pressure at 2) + (Pressure caused by the fluid)
    = P2 + ρg(h+Δh)
