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.
![A consumer upset with the latest trend of postal rate increases has decided to try to send letters by balloon even though they may not reach their intended destinations. A \(6.00 \times 10^4 \, \text{cm}^3\) gas-filled balloon will provide enough lift for a 46.8 g package to be accelerated upward at a rate of \(2.65 \, \text{m/s}^2\). For these circumstances, calculate the density of the gas the consumer fills the balloon with. The acceleration due to gravity is \(g = 9.81 \, \text{m/s}^2\) and the density of air is \(\rho_{\text{air}} = 1.16 \, \text{kg/m}^3\). Neglect the mass of the balloon material and the volume of the package.
\[
\rho = \quad\quad \text{kg/m}^3
