A 1.00-kg beaker containing 1.50 kg of oil (density = 916 kg/m³) rests on a scale. A 2.40-kg block of iron is suspended from a spring scale and is completely submerged in the oil (see figure below). Find the equilibrium readings of both scales. top scale bottom scale
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.
![**Experiment Setup: Measuring Equilibrium Readings**
In this experiment, a 1.00 kg beaker containing 1.50 kg of oil (with a density of 916 kg/m³) is placed on a scale. Above it, a 2.40 kg block of iron is suspended from a spring scale and is completely submerged in the oil. The objective is to find the equilibrium readings of both scales.
**Diagram Explanation:**
- **Top Part**: The spring scale is attached to an iron block, which is fully submerged in the oil within the beaker. The spring scale will measure the tension in the spring, as the iron block is buoyed by the oil.
- **Bottom Part**: Below the beaker-oil setup, there is a traditional scale that measures the total weight of the beaker, oil, and the buoyant force acting due to the submerged iron block.
**Required Calculations:**
- **Top Scale (Spring Scale)**: This measures the force (in Newtons) due to the weight of the iron block minus the buoyant force exerted by the oil on the block.
- **Bottom Scale**: This measures the combined weight of the beaker, oil, and the additional force due to the buoyancy acting on the iron block.
Please input the equilibrium readings for both the top and bottom scales to complete the analysis:
- Top Scale: ______ N
- Bottom Scale: ______ N
Understanding these measurements helps in comprehending the principles of buoyancy and equilibrium in fluid systems.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5162d869-5511-48a2-94b1-17aaced0b098%2Fdc35f8c9-f3d8-4edc-8e7d-62aa3ca8b460%2Fj0qewt_processed.png&w=3840&q=75)
