Water Force

In the record of the hydrology day, there seems to be a big difference in flow pattern between small slopes and large slopes. When we get off the water from a small amount of slope, the water does not flow anywhere, it just floats in the puddle without sprinkling too much water. But on a steep slope, the water flows much faster and forms a flow of water entering the spill along the sand. It is formed accurately and you can reliably say that it is taking place on a steep slope.

Consider a water column in hydrostatic equilibrium state. All the forces applied to water are balanced and the water does not move. In any water drop, the two powers are balanced. One is gravity, which acts directly on all atoms and molecules inside. Gravity per unit volume is ρ g. Where g is the acceleration of gravity. The second force is the sum of all the forces the surrounding water exerts on its surface. The force from below is greater than the force above only the amount needed to balance the gravity. The normal force per unit area is the pressure p. Since the average force per unit volume in the droplet is the pressure gradient, the force equilibrium equation is

Various actions - reaction force is inherently obvious. Let's consider the propulsive power of fish underwater. The fish pushes the water behind with the fin. But pushing water only speeds up the flow of water. As forces are the result of interaction, water must also push the fish forward and push the fish into the water. The magnitude of the water force is equal to the strength of the fish and the direction of force applied to the water (backward) is opposite to the direction of the force of the fish (forward). Each action has a (direction) reaction that is equal (magnitude) opposite. Action - fish swims by reaction force

A mountain of water came back. This pushes water down. The power of water is transmitted through the sea and moves the underwater force several hundred kilometers. When water flows through the sea, water may reach 800 kmh. Energy is underwater, the surface is not obvious. When this force passes through the sea, it may eventually reach the coast. At this point the seawater becomes shallower. But the underwater energy is still the same. It compresses energy and boosts water. This is how energy is transferred from lowway to surface wave.
