Wait, at 3:25 you said the area spacing between impeller blades is increased radially to convert kinetic energy to pressure energy.And the argument you give is that as per Bernoulli equation increase in area leads to decrease in velocity. But the thing is the impeller blade is supplying energy to the water and therefore Bernoulli equation cannot be applied. Moreover the reference frame is also not inertial but a rotating frame which imparts centrifugal force which we should also take into account. The reasons should be explained taking into considerations these two factors also.

Why is it beneficial to have the increasing channel area toward the outside of the impeller? Also every flow simulation I have seen shows the velocity of the fluid being very high at the outermost part of the channel, which makes sense because that's where the vane linear velocity is at its highest. Wouldn't this expansion in area create unwanted low pressure at the outermost portion of the channel? I understand that this increase in area is sort of inherit to the design of a round object haha, but has anyone done flow tests on an impeller with widening vanes to keep the channels the same area? They must have right?

wouldn't it be better if there was no viscous drag on the outside of the closed impeller?

Why in eye of impeller there's nagative pressure and why it's suck the Fluid?

The pump impeller draws liquid away from the suction of the pump, which just like sucking on a straw is going to attempt to form some sort of vacuum. This is why net positive suction head to prevent cavitation is very important.

Hi John, Very good presentation as usual I have some doubts 1. Why should the number of channels be less for fluids with high suspended solids and more for fluids with less suspended solids?? 2. Though fully closed impellers have the highest mechanical strength compared to the other two types, why aren't they used for pumping slurries and why open impellers having the lowest mechanical strength are being used for pumping slurries ?

Regarding your second question, slurry pump impellers are often closed. In fact they will almost exclusively be closed because the front shroud has pump out vanes on the outside to prevent frontal recirculation. The only time you will have an open impeller on a slurry pump is if you have stringy fibrous material, froth or the pump size is really small.

If a centrifugal pump is fails to deliver water or other expected fluid when first started, what could be the cause? A.pump is not prime B. Impeller flood C. Water seal is pluggged D. Seal ring is improperly located. Sir, can answer this question? Thank you .

how does increasing area increase the pressure? isnt pressure force per area and any unit of increase in pressure should decrease it?

Not in a system that’s flowing. The simplest way to understand it is that in fluid flow, there’s three forms of energy. Height or potential, kinetic or velocity, and pressure. Now take two points in the flow. The total energy at the two points have to equal. If you add up the three forms of energy at point A, it has to equal the energy at point B. If any form of energy goes up, another form has to go down an equal amount. The easiest example is if a pipe goes higher by 1 foot, an increase in height or potential, the pressure has to drop by 1 foot. About .4 psi for water. If velocity drops with an increase in area, pressure has to increase by an equal amount. This is what’s happening in the impeller and also the volute. Of course, point B will actually have a little less energy than A because some will be lost to friction.

I recently was running a pump application calculation switching from a closed vane impeller to a semi open vane impeller... the speed needed to pump the same volume decreased by approximately 50rpm with the semi open impeller. Which, will require a drive change... WHY?!
