Calculate Absolute Pressure ?

    1. The problem statement, all variables and given/known data

    Calculate Absolute Pressure?
    (1) A Lake has average temperature of 10°C and a maximum depth of 35m. The barometric pressure at the lake is 598mmHg. At the deepest part of the lake, determine the absolute pressure in Pascals. Specific weight of the water in the lake 10degreeC is 9.804Kn/m 3


    2. Relevant equations

    Pabs = Ps + Density * specific weight * Height

    3. The attempt at a solution

    598 mmHg = 79.72 KPA

    79.72 * 103 PA + ( 1000 kg/m3 * 9.804 * 103 pa/m3 *10 mt)

    Pabs = 98 * 106 PA

    Thanks for the help, silly mistake! :uhh:

    79.72 * 103 + (1000 * 9.804 * 103 * 35)

    =343 * 106 PA

    am on the right track?
