You and some friends take a hot-air balloon ride. One friendis late, so the balloon floats a couple of feet off the ground as youwait. Before this person arrives, the combined weight of the basket and people is 1220 kg, and the balloon, which contains 5980kg of hot air, is neutrally buoyant. When the late arrival climbsup into the basket, the balloon begins to accelerate downward at0.10 m>s2. What was the mass of the last person to climb aboard?
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.
