Let rho be the density of a liquid and g be the acceleration due to gravity. A vertically oriented cylindrical tank is 10 meters high and has a base radius of 1 meter. Suppose this tank is half full of liquid and that it will be completely emptied using a pump level to the top of the tank. Letting y=0 correspond to the base of this cylinder, the work required to pump out all the liquid is: None of the other listed answers are correct. W=1²5² (10-y)dy OW=T π fo (10-y)dy OW=T Tº(10-y)dy π fº y dy OW=T W = ²(10-y)dy 10²
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.
