2. CAVITATION: It is also suction loss by forming cavity of a volatile liquid whose NPSH(a) is belowNPSH(r) eg..Choking or blockage of suction strainers, closing of suction valve of apump when running.
3. VAPOUR LOCK: This is also loss of pumping due to blockage in discharge of a pump..closing of discharge valve and running for more time..running the pump with in adequate minimum flow..liquid above boiling point
Hence Cavitation, Vapour Lock and Primimng loss are different

What are the two types of cavitation?
The two types of cavitation are inertial cavitation and non-inertial cavitation. Inertial cavitation occurs when rapid changes in pressure cause the formation and collapse of bubbles. Non-inertial cavitation involves the stable growth and collapse of bubbles due to continuous low-pressure conditions.
How the cavitation in reaction turbines can be avoided?
Cavitation in reaction turbines can be avoided by ensuring that the turbine is properly designed and operated within the specified operating conditions. Proper selection of materials, maintaining the right flow rate, and avoiding sudden changes in pressure can also help prevent cavitation. Regular maintenance and inspection of the turbine are important to detect and address any signs of cavitation early on.
What is difference between cavitation and supercavitation?
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
Why is cavitation detrimental to a pipe system?
Cavitation is detrimental to a pipe system because it can cause erosion of the pipe material due to the formation and collapse of vapor bubbles. This can lead to structural damage, leaks, and reduced efficiency of the system. Over time, cavitation can weaken the pipe, leading to potential failures and costly repairs.
What is caviation?
Cavitation is the formation of vapour cavities in a liquid, caused by rapid changes in pressure. These cavities collapse with great force, leading to damage in equipment and machinery operating in the liquid. Cavitation can occur in pumps, propellers, and other hydraulic systems.
What are the two types of cavitation?
The two types of cavitation are inertial cavitation and non-inertial cavitation. Inertial cavitation occurs when rapid changes in pressure cause the formation and collapse of bubbles. Non-inertial cavitation involves the stable growth and collapse of bubbles due to continuous low-pressure conditions.
When was Emerson Cavitation Tunnel created?
Emerson Cavitation Tunnel was created in 1949.
What is a cavitation plate on a boat?
A cavitation plate is the adjustable metal plate that runs along the bottom of the transom on a V-drive. Some people call the flat metal plate on an outboard or outdrive a cavitation plate but the correct name is anti ventilation plate and cavitation and ventillation are not the same. It is similar in function to Trim Tabs. A cavitation plate is used to adjust the trim of a V-Drive and keep the nose on the water. Here is a link to a picture on PerformanceBoats dot com In this picture of a V-drive, the cavitation plate is anodized red.
How cavitation can be eleminated in a pump?
cavitation is caused when vapour pressure in the fluid in higher equal to the surrronding presure. in the case of centrifugal pump, when the hydraulic pressure (due to height) in the fluid falls below the vapour pressure of the fluid itself, cavitation wil occur.
How to fix a cavitation problem on my boat?
To fix a cavitation problem on your boat, start by inspecting the propeller for damage or wear, as a damaged prop can exacerbate cavitation. Ensure the propeller is appropriately sized for your boat and consider upgrading to a more efficient design if necessary. Additionally, check the alignment and condition of the drive system, as misalignment can contribute to cavitation issues. Lastly, adjust the trim angle while operating to optimize performance and reduce cavitation effects.
What has the author Minao Kamegai written?
Minao Kamegai has written: 'Underwater explosions and cavitation phenomena' -- subject(s): Underwater explosions, Cavitation
What is priming input?
A priming input, also known as priming read, is the statement that reads the first input data record prior to starting a structured loop.
What does looked to their priming mean?
The phrase "looked to their priming" in The Highwayman means that the soldiers were preparing to fire their weapons. Priming was arming the weapon to fire it against an enemy.?æ
What causes cavitation in a pump?
cavitation is caused when vapour pressure in the fluid in higher equal to the surrronding presure. in the case of centrifugal pump, when the hydraulic pressure (due to height) in the fluid falls below the vapour pressure of the fluid itself, cavitation wil occur.
Are rotary pumps self-priming and if not how do I prime it?
Some rotary pumps are self-priming when dry. These pumps have a priming chamber that automatically does the self-priming when the pump is not in use. To prime a pump yourself, the priming plug should be removed. Water should then be poured into the pump. The entire priming process should take no longer than five minutes. If it takes longer than that, it could be indicative of a mechanical problem.
Does the cerebullum associate with priming?
Priming is associated with what part of the brain the amygdala cortex striatum or the cerebellum?
What is the Priming Handle on the Raider CS 35?
The priming handle is simply the handle which you use to reload.
