Why does pressure decrease as area increases?
As you correctly identified, mechanical potential energy (pressure) is converted into mechanical kinetic energy (velocity) and so the pressure must decrease as the velocity increases while the liquid flows through the nozzle.
What happens to the pressure when the area increases and decreases?
The pressure exerted on a surface by an object increases as the weight of the object increases or the surface area of contact decreases. Alternatively the pressure exerted decreases as the weight of the object decreases or the surface area of contact increases.
Why does the speed of a liquid increases and its pressure decreases?
The speed of a liquid flowing through a pipe increases and its pressure decreases when liquid passes through a narrow constriction in the pipe. Since velocity is high at the narrow constriction, hence the pressure is low there.
What will happens to pressure when area increases?
As pressure and area are indirectly proportional to each other . so , if area increases , pressure decreases.
Why does pressure decrease when area decreases?
Some energy is in the random motion of molecules, which we observe as pressure. This change makes the pressure drop. Pressure is inversely proportional to area, if everything else stays the same. In this case, the energy that causes pressure is converted to another type of energy, so both pressure and area decrease.
What is the relationship between pressure and area?
The relation between pressure and area is that pressure and area are inversely proportional to each other. That is when area decreases pressure exerted on that area increases. When area increases pressure exerted on that area decreases.
What is pressure what happens to the pressure when area on which it is applied increases?
Pressure is the amount of force acting on a unit area of a surface. That is, pressure and area on which the force is applied has an inverse dependance. Keeping force constant, if the area on which the force applied is increased, the pressure decreases.
Why does the speed of a liquid increase and its pressure decreases when a liquid passes through constriction in a horizontal pipe?
Consider a horizontal constricted tube. Again, since A1 > A2, the bracketed term is positive so that p1 > p2 . Thus, as the fluid passes through the constriction or throat, the higher speed results in lower pressure at the throat.
What happens to the pressure when you increase the force acting on an area and area of the surface?
when area increases pressure decreases. And when the force acting increases pressure increases. Explanation: Because pressure is directly proportional to force applied and is indirectly proportional to the area in contact.
Why do nozzles decrease pressure?
The pressure drops in a convergent nozzle because of the Bernoulli Principle. A nozzle is a spout on the end of a hose or pipe used to control the movement of a fluid like water or air. The energy in this random motion is converted into faster forward motion, known as stream flow. This change makes the pressure drop.
What are the relationships between pressure and force and between pressure and area?
Since we found F = PA, we see that the force exerted by a pressure is directly proportional to the area acted upon as well as the pressure itself. The force exerted on the end of the tank is perpendicular to its inside surface. This direction is because the force is exerted by a static or stationary fluid.
