Part A Take the density of the crown to be Pe. What is the ratio of the crown's apparent weight (in water) Wapparent to its actual weight Wactual? Express your answer in terms of the density of the crown pe and the density of water pw.
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.
Given:-
We have a weight tool as given in the figure.
On the left side of the weight machine with the water and the crown and right side of the weight machine, we put the weight according to the weight of the left side and balance it.
The density of the crow is
Find:-
what is the ratio of a crow's apparent weight? Wapparent to the actual weight Wactual ?
