A large weather balloon has a volume of 2000 m3 and a total weight of 800 N is filled with gas. The basket attached to the balloon has a weight of 1200 N and inside the basket there is a total mass M. The balloon starts from rest an ascends a total distance of 25 meters in 5 seconds. If the density of air is 1.20 kg/m3 and the average density of gas is 0.179 kg/m3, what is the value of the mass M in kg. Hint: the system has an acceleration Show a coordina
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.
