Question
A rigid, hermetically sealed container contains two fluids: water (103 kg / m3
) and air.
A pressure gauge, attached to the top of the tank, indicates a pressure
40 kPa vacuum gauge. If the atmospheric pressure of the place is 105 Pa and the water inside the
container has a height of 30 cm, determine the absolute pressure at the bottom of the tank.
Consider that the gravitational acceleration of the place is 9.8 m / s2
.
a) 60 kPa
b) 62.94 kPa
c) 142.94 kPa
d) 57.06 kPa
