What happens to pressure in convergent nozzle?
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area. To maintain a constant amount of fluid moving through the restricted portion of the nozzle, the fluid must move faster.
What happens to velocity in the converging nozzle?
In fact, in the converging part of the nozzle, the flow speed increases, while the pressure, density, and temperature decrease. The flow speed attains its maximum, subsonic value at the throat of the nozzle, while the pressure, density, and pressure simultaneously attain minimum values.
What happens to pressure in a nozzle?
Originally Answered: Pressure is indirectly proportional to area, but in a nozzle, the area decreases but the pressure also drops which converts the same into velocity. But why does this happen. As by physics, pressure should be increasing but it decreases.
Why does velocity increase in a nozzle?
Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy.
What is the relationship between pressure and velocity in a pipe?
Velocity and Pressure are inversely proportional to the Area of cross section of the body through which a fluid is flowing. consider figure 1: An ideal fluid(that does not has viscosity(friction) among its particles ) flows through the pipe.
Why does pressure drop when velocity increases?
By the law of conservation of energy, the total energy remains constant and thus when the velocity increases the kinetic energy also increases which causes decrease in pressure energy.
What happens to pressure and velocity in a diverging duct with subsonic airflow?
For subsonic air flowing through a convergent duct, it decreases pressure and increases velocity. The opposite happens when flowing through a divergent duct.
