Key words Fluid Pressure Specific Mass Surface Stress Capillarity Viscosity Bernoulli Law Pascal Law Archimedes Law Fluid or liquid is substance that flow all of its part to other places in the same time. The substance shapes in general divided into three solid substance liquid and gaseous substance. Based on their size and form substances have fixed shape and volume but its form changes suitable with the container while gas do not has fixed form so both have abilities to flow. Substance that able to flow or give little barrier toward the form change when be pressed is called as flow substance where flow substance is substance that flow all of its parts to other place in the same time. Based on its movement there is two kinds of fluid that is static and dynamic fluids. Pascal law to increase the elevation of water surface is instrument that can be used to visualize work principle of Pascal law. Useful for education and society is expected be useful for readers and able to open insight about hydraulic aspects. Based on Pascal law it is obtained principle that with small force able to produce larger force. Airplane able to be lifted to air because the air rate that pass through the airplane wings and airplane is not like rocket that is lifted up because of action and reaction between gas that spurt by the rocket. The rocket spurt the gas to backward and as reaction the gas push the rocket forward. So rocket can be lifted while no air but airplane unable to fly if no air. The wing sections of airplane have more sharper rear side and upper side that is more curved than the lower side.
