An object that has a Gs = 0.95 is found floating on a certain liquid with Gs = 1.06. If the
volume of the exposed object is 950 cu.m, determine the total volume of the object.
In a tank with a height of 1 meter, open to the atmosphere at the top, there are two immiscible liquids (which do not mix) and whose densities are 13,600 kg/m3 and 750 kg/m3, respectively.
The tank is completely full and each liquid occupies half of the container. If the atmospheric pressure of the place is 105 Pa, at what depth, measured from the top of the tank, is the value of the gauge pressure equal to half the value of the atmospheric pressure of the place? Consider that the gravitational acceleration of the place is 9.8 m/s2?
