A cylinder with cross-section area A floats with its long axis vertical in a liquid of density p. Pressing down on the cylinder pushes it deeper into the liquid. Find an expression for the force needed to push the cylinder distance a deeper into the liquid and hold it there. Express your answer in terms of the variables p, A, and a. F = Submit Part B IV— ΑΣΦ 1 → W = A 4.0-cm-diameter cylinder floats in water. How much work must be done to push the cylinder 20 cm deeper into the water? Express your answer with the appropriate units. Request Answer O Value Units ?
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.
