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.
![**Problem:**
Find the volume in m³ of a metal bar if the bar has a mass of 48 kg and the density of the bar is 7.3 g/cm³.
**Solution:**
To find the volume of the metal bar, we can use the formula:
\[ \text{Volume} = \frac{\text{Mass}}{\text{Density}} \]
**Given:**
- Mass = 48 kg
- Density = 7.3 g/cm³
**Steps:**
1. First, convert the mass from kilograms to grams:
\[ 48 \, \text{kg} = 48,000 \, \text{g} \]
2. Use the formula to find the volume:
\[ \text{Volume} = \frac{48,000 \, \text{g}}{7.3 \, \text{g/cm}^3} \]
3. Calculate the volume in cm³:
\[ \text{Volume} \approx 6575.34 \, \text{cm}^3 \]
4. Convert the volume from cm³ to m³:
\[ 6575.34 \, \text{cm}^3 = 0.00657534 \, \text{m}^3 \]
**Result:**
The volume of the metal bar is approximately 0.006575 m³.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd1d700aa-072a-4ff7-be1d-cdca0f10aa9d%2F45d99bfe-671a-4d00-b893-2ed9707036c9%2Fa1mjimd_processed.jpeg&w=3840&q=75)
