Why the divergent section of a venturimeter is longer than the convergent section?
The divergent section of a venturi meter is longer than the convergent section to gradually decrease the fluid velocity and increase the pressure after the throat, which helps in recovering some of the kinetic energy as pressure energy, reducing energy losses and ensuring accurate flow rate measurement. This design also helps to minimize turbulence and pressure drop in the system.
Why the divergent angle of venturimeter is lesser than convergent part?
The divergent angle of a venturimeter is designed to be lesser than that of the convergent part to minimize flow separation and turbulence as the fluid exits. A gentler angle in the divergent section allows for a smoother transition from high velocity to low velocity, reducing pressure losses and ensuring accurate measurements. This design helps maintain continuous flow and improves the efficiency of the fluid measurement process.
Does divergent plate boundarys produce the largest earthquakes?
Divergent plate boundaries typically produce smaller earthquakes compared to convergent plate boundaries, where tectonic plates collide. At divergent boundaries, tectonic plates move apart, creating new crust, which generally results in less intense seismic activity. In contrast, convergent boundaries often involve subduction, leading to significant stress accumulation and larger earthquakes. Therefore, the largest earthquakes are generally associated with convergent, rather than divergent, plate boundaries.
What is a divergent beam?
A divergent beam is a type of radiation beam that spreads out as it travels away from its source, rather than remaining focused. This can result in a wider area of exposure compared to a convergent beam. Divergent beams are commonly used in certain types of imaging techniques, like X-rays.
Why the divergent part of venturimeter is longer than convergent part?
Actually when the flow emerges from the throat area of venturi to enter into the diverging section, their is a negative pressure gradient i.e, in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient, there is boundary layer separation, in simple terms, the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can't recover the pressure fully leading to head loss. So if divergent section is long that means more gradual diverging section, due to which the adverse pressure gradient is less so less chance of boundary separation and hence less loss. Also large diverging section will ensure proper development of flow, i.e. fluid sticking to the wall back after separation.
Which times divergent cone is bigger than convergent cone in venturimeter?
why lenght of divergent cone is larger than convergent cone in venturi meter
Why divergent cone in venturi meter is longer than convergent cone?
The divergent cone in a Venturi meter is longer than the convergent cone to ensure a gradual expansion of the fluid flow. This gradual expansion minimizes turbulence and pressure loss, allowing for more accurate measurements of flow rates. A longer divergent section helps to maintain smoother flow patterns, which is essential for the Venturi effect to function effectively. In contrast, a rapid expansion would lead to flow separation and energy losses.

What is the difference between convergent divergent nozzle and venturi tube?
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
Why is the boundary of the Nazca Plate considered divergent rather than convergent?
The Nazca plate has more than one boundary. The western and northern boundaries are divergent as the plates are moving apart from one another. However, the Nazca plate's eastern boundary is convergent as it collides with and subducts under the South American Plate.

Therefore, the largest earthquakes are generally associated with convergent, rather than divergent, plate boundaries.
Do convergent plate boundaries involve the process of rifting?
Yes, convergent plate boundaries involve the process of rifting where tectonic plates move apart, leading to the formation of new oceanic crust. This process typically occurs at divergent plate boundaries, such as mid-ocean ridges, rather than at convergent plate boundaries where plates collide or subduct.

Is new crust created at a convergent boundary?
No, new crust is not created at a convergent boundary. Instead, at convergent boundaries, two tectonic plates come together and one plate is usually forced beneath the other in a process called subduction. This process can lead to the destruction of crust rather than the creation of new crust.
What are the advantages and disadvantages of flow nozzle?
One disadvantage in the convergent-divergent nozzle as a shock wave can take place in the nozzle A nozzle is a device that converts pressure energy to kinetic energy (increasing fluid velocity on the account of static pressure) For a convergent nozzle there is no disadvantages as it can raise the fluid velocity only for the sonic speed the convergent-divergent type raises the velocity to over than sonic speed making supersonic flow, this could make a shock wave in the nozzle that turns the supersonic flow to subsonic flow
