What Factors Affect Absolute Pressure at Lake Depths?

[Macca1986]

Homework Statement

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

Homework Equations

Pabs = Ps + Density * specific weight * Height

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

Hi Macca1986! Welcome to PF!

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

erm …

35 metres! ​

Thanks for the help, silly mistake!

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

=343 * 10⁶ PA

am on the right track?
