A 5.00kg brick is placed on a scale, to reveal that the weight is 49N. Next to the scale is a resevoir containing 100.00L of water. There is a scale in the water. The brick is then placed in a resevoir and is placed on the underwater scale. The scale reads 24.50N, and the volume of the water is now 102.50L. (The density of water is 1 g/cm^3). 1. Calculate the volume of water displaced. 2. Calculate the mass of the water displaced. 3. How does the mass of water displaced compare to the mass of the brick? 4. What is the apparent weight of the brick? 5. Calculate the Buoyant force acting on the brick.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
