    Inicialmente no ramo a ser tampado no nível do liquido.

    Par = Patm

    Par = 13,6.76 = 1033,6 gf/cm²

    Quando tampado

    Par + 1,8.h = Patm + 1,8.h + 1,8.10 --> Par = 1033,6 + 18 = 1051,6 gf/cm²

    Dado que Pi.Vi = Pf.Vf (com os dados disponíveis somente considerando o processo adiabático é possível resolver).

    Vf / Vi = Pi / Pf --> A.hf / A.50 = 1033,6 / 1051,6 --> hf = 1033,6.50 / 1051,6 = 49,14 cm

    Δh = 50 - 49,14 = 0,86 cm
