What is the meaning of the word 'priming'?
Priming in painting refers to putting an initial coat of a preparatory agent to ensure the paint sticks to the surface. Priming with reference to scientific experiments refers to the cleaning of a workspace or instruments before an experiment.

Why is the heart made up of two separate pumps?
The heart is made of two separate pumps because on takes blood in while the other pumps it out.
What pumps blood to the feet?

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.
Toyota fuel pump not priming?
Spray a starter fluid into the intake to get the engine running. If the fuel pump does not start pumping, it is defective, or the fuel filter is clogged. These pumps are self priming.
How many types of pump use in industries?

Is pioneer a registered trademark for submersible pumps?
The phrase Pioneer Pump is a registered trademark of Pioneer Pump, Inc., for use with "Electric and engine driven water pumps for use in pumping abrasive fluids and waste, namely, vacuum assisted, centrifugal, self priming and hydraulic submersible pumps and parts therefor."
What is pump-priming?
To spur economic activity through investment. The term comes from the way old pumps worked. You had to use water to prime the suction valve so that you could get more water.
What is priming in the centrifugal pump?
The centrifugal pump has to be filled with fluid before it can start to move fluid. They cannot suck fluid in by creating a vacuum in the pump chamber like some other types of pumps.
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 is priming in pumps?
Simply put - a pump is a device that moves fluid - generally from a lower level to a higher level against gravity. To do this - the device must already be submerged in the fluid, since it cannot pull up the fluid from a lower level to its own level and then discharge it to a higher level. This will require it then to suck air through an inlet pipe (submerged in the fluid) to create vacuum that will then pull up the fluid to it's own level. Pumps that cannot do the air sucking - needs, what is called priming. The inlet pipe is fitted with a one-way (up - only) valve, called the foot-valve, fitted at it's mouth which is submerged in the fluid. The pipe then is filled from outside with the same fluid till it tops up till the pump. The foot-valve prevents the fluid from draining away (up-only). This procedure is called "priming the pump". Once primed, the pump remains submerged in the fluid all the time unless the foot-valve leaks. Starting the pump in this condition allows the fluid to be "pumped" through the discharge pipe and all is well. Priming is done only once, till the foot valve leaks.
