Bernoulli s Equation tells us that if the velocity of the fluid is high in (low area region) the pressure has to be low, can any one explain why (do not explain me the mathematics i understand that well) just a physical explaination needed about why does it actually happen.

Answer:
rnoulli's principle can be applied to various types of fluid flow, resulting in various forms of Bernoulli's equation. The simple form of Bernoulli's equation is valid for incompressible flows (e.g. most liquid flows and gases moving at low Mach number). More advanced forms may be applied to compressible flows at higher Mach numbers (see the derivations of the Bernoulli equation).
Bernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of kinetic energy, potential energy and internal energy remains constant.[2]: § 3.5 Thus an increase in the speed of the fluid – implying an increase in its kinetic energy (dynamic pressure) – occurs with a simultaneous decrease in (the sum of) its potential energy (including the static pressure) and internal energy. If the fluid is flowing out of a reservoir, the sum of all forms of energy is the same on all streamlines because in a reservoir the energy per unit volume (the sum of pressure and gravitational potential ρ g h) is the same everywhere.[6]: Example 3.5

Answer:
The Bernoulli Equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids. In the high velocity flow through the constriction, kinetic energy must increase at the expense of pressure energy. ...
