A box shaped vessel 24m x 6m x 3m displaces 150 tons of water. Find the draft when the vessel is floating in salt water? 5. A ship lying in the mouth of a river in wate of density 1024kg per cu.m and the displacement is 12000 tons. Tthe ship is to proceed up river and berth to dock at water with density 1008 kg per cu.m with the same draft. How much cargo ust be discharged? 4.
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.
